Well I want this plugin to be simple, cross-platform, and work under all 
engines.  You could certainly write a POE-based backend for these things 
if you have the need.  I actually have a POE backend for one of my Cat 
apps that does complex auth checking for many users.  Definitely the way 
to go for async stuff.
