[JDEV] Distributed design of jabber

[temas]

dpsm is me.  It works right now (requires kernel module for devpoll
support).  It's not fully tested, but that should be happening more this
week.  Give it a go and help develop it and I'll love you =)

Not sure on mod_farm right now, haven't looked in a while.
