I didn't read the whole thread, but I'd like to point out something.
An e-pipe with an atomizer from any ecig would be useless. An e-pipe can't be just an ecig in a nicer body and with bigger batts. I want it to stand on my desk, next to my laptop docking station. I want to vape all day without taking any care of it. If it's meant to be stationary, then it has to be a
vaping station! That's what every geek wants!
If I were to buy an e-pipe, I'd want:
- a totally different atomizer design - one that lasts for ages, doesn't clog, get flooded or dry out
- a new liquid delivery system - no carts, no burnt plastic taste
- not having to top it up for a week (10ml
tanks)
- removable
tanks, so I can switch flavors (maybe even easily washable atty, so I don't mix tastes)
- circuit intended to be plugged in all the time without destroying the battery with constant recharging after each puff
And since it's an e-pipe, you don't have to miniaturize anything to fit in an ecig. I want it big and sturdy. For example, the liquid delivery system can be controlled electronically, dripping just as much as needed. The atty doesn't have to be a thin wire coil that fails after a couple of months and cant be scrubbed (or even touched). It can even be AC powered with strong gel accu sold separately!
Now that would be the e-pipe for me!
PS: Ludo, if I've hit the jackpot, just PM me when I'll be getting a prototype. 
I'll sign anything you want in my own blood, just give me one if I'm right about it!
