Tim is right, but what he means is: that plugin (vB-Ispy) creates a massive server load, very much like an embedded live chat plugin, so we would need an equally massive reason to install it
Can't argue, it's a lot of fun though...
At some stage we will look at a new concept whereby we serve our database off a standard dedicated server and have the web-facing servers as cloud servers that can have capacity added on-the-fly without investing in a new box every time the load spikes. At that stage it will be much easier and cheaper to add more functionality. That system isn't fully developed right now.
At the moment, adding a plugin like that essentially means we'd need to add a server, which is a fair old chunk of beer coupons for just one feature that isn't a major benefit.
Sorry
