Very good point. I think I also remember someone saying that the amount of caffeine needed to actually give an effect would be so large that the end product wouldn't be much of a liquid anymore, and would taste horrible.
Caffeine extract?

ok...understood. not impossible, just impractical. maybe i'll soak some snus in some lol j/k
Since they're out of stock, here's a link to another supplier I bookmarked back when I was considering trying it at some point:
Caffeine Powder - 4 oz - ZIN: 512214
Caffeine does dissolve in water, so I would think there is hope for vaporizing it, but it may leave a residue and end up killing your atty.
I've not tried it yet, so I don't know if it would be safe or even work. Maybe someone with more of a chemistry or pharmaceutical background than I could chime in here and support my guesses below or refute them if I am off?
As far as safety goes, caffeine's LD50 is estimated at 150-200 mg/kg with an ODs beginning at around 300 mg (compared to a LD50 of 0.5-1.0 mg/kg for nicotine). Given that info, vaping 3 mls of 24 mg/ml e-liquid quickly would be dangerously high for most people.
Room temperature water can only dissolve 21.7 mg/ml of caffeine (VP/PG may be more or less, but I can't find info on that and the amount of nicotine and/or flavorings in the liquid may have an effect as well). So even at the maximum saturation of caffeine, this same 3 ml of liquid would only give a maximum of about 60 mg of caffeine, or a little bit more than a 12oz can of Mt.Dew.
So even assuming full absorption (which I assume, just like nicotine, would not occur) and vaping the 3 mls quickly enough to have all of the caffeine in your system at once would be similar to chugging a can of Mt. Dew while giving most people one hell of a headache or even sending them to the hospital for nicotine OD.
To me this really doesn't seem like it's worth the trouble since I am constantly drinking something just to keep my vaping from drying out my throat and can get my caffeine that way.
Again I'm not a chemist, so take these conclusions with a large grain of salt.

And therein lies the problem; if the caffeine doesn't reach it's vaporization temperature but the liquid does, then it will be left behind as a residue.
if the camera wasnt on the back side of the phone i bet someone would make one, even though it wouldnt help any
Heh, good thing it's fake. My brain was churning trying to comprehend how it's possible to inhale 150mg of caffeine in a single shot.
Pure caffeine is extremely bitter. I hate to admit it, but I've done a "line" of the stuff before (probably less than 50mg) and it left me with horribly bitter tasting post nasal drip.

That's the other problem I forgot to mention. The bitterness is hidden well when paired with some thing with a strong flavor like coke or even sugared water. But I doubt our vape would be able to mask the bitterness and might well just end up with something that tastes disgusting. At these concentrations though, there may just not be enough to taste.
Ethyl Maltol or FlavourArt's MTS Vape Wizard might reduce the bitterness. Maybe not enough, and either might reduce the flavor too much, but it might be worth a try.
on the whole sparks thing I thought they caught wind of this some time ago and removed the caffeine?... could be wrong if I am tell my local mini-mart they're violating fda regulations 
Now let me get this straight I thought caffeine had to be digested and metabolized in order to be effective but if it was vaporized it would still have stimulating effects? (not that I would the concept seems like it'd taste nastier that hell) and if the product was vaporized wouldn't that be quite dangerous? Wouldn't it rapidly reconsolidate into the powdered form when atomized and inhaled? For example methamphetamine when freebased converts into a vapor but it quickly reconstitutes into it's crystal form. Hence why many "tweakers" refer to an ailment known as "crystalized lungs" where the vaporized product was not exhaled quickly enough and coated the users throat, would this not happen with a powdered product such as caffeine? and doesn't that happen with true menthol e-juices using menthol crystals not just "mint" flavoring? even though the crystal has been atomized it is still present to some part in its crystal form is it not?

Actually, when I made that video yesterday I tried inhaling some of the vapor. It was completely orderless and didn't leave any kind of after taste. It was only a small amount though.
I still don't think it's possible or even practical to vape it from an e-cig. Maybe I'll experiment some when I get the time. I only have plain glycerin to mix it with. I don't want to waste any of my good juice on experiments.
EDIT: OK, I just dissolved ~25mg of caffeine into a 1ml 80/20 mix of glycerin and water. I had to heat the mixture for the caffeine to dissolve; which it did nicely, turning into a crystal clear mix. Unfortunately, once the liquid cooled it turned completely solid.
I'm not going to try it again, but it's obvious the caffeine amount would need to be greatly decreased to keep the mix a liquid.
Conclusion: Caffeine vape myth - TOTALLY BUSTED!!!!

They might have, I don't know. I haven't drank one in quite a while so it's not like I'm going to be THAT disappointed.
Just an FYI. Most mint flavored essential oils (spearmint, peppermint, wintergreen, etc.) have a high percentage of pure menthol in them which gives them their feeling of coolness. The other thing is from my experiences, menthol crystals seem to stay dissolved in ~60 proof vodka above 65-70 degrees. So if my mix recrystallizes at all, I just warm it in my hands for a few seconds. I doubt there would be a problem in you lungs.
Besides, I smoked menthol cigs for years and didn't hack up crystals, so I doubt menthol vapor would do any worse.
