[Twisted-Python] Twisted Hosting and Twisted in the Cloud

So the model's base or metaclass would handle synchronization and the rest
of the app would have to be effectively stateless with the cloud handling
routing and instantiation inherently?  That would work but be a big step
form the way I'm working today where my model handles permanent storage and
my resource instances handle non-persistent game data internally.  Do you
have a mailing list or wiki where you're laying out ideas?  I'd be
interested to join in on that.
