Wonderful!  Perl can be a big boon to Jabber, and I just haven't had the
time to really work on it yet... although I know Thomas Charron has done
some.

It hasn't been talked about much yet, but at this point a user is really
tied to their server, similiar to how your email client is tied to your
email server.  On the same note, providing forwarding will definately be
added to one of the modules so that messages can be forwarded to your new
location like in email.

The other thing I've been mulling around, is that any of the common
settings for your user account(name/password/security/preferences/etc) 
could be expressed in a common XML structure, and could be saved by the
user or automatically sent from the old server to the new server, but that
is a discussion that will have to wait till we have something to really
test it with.

Absolutely, 100%, please yes!  The whole thing can be written in perl :)

My take:
 Modules:
	A mod_perl needs to be written to do this, similiar to Apache
 Clients:
	A perl module, maybe Net::Jabber could be written to make this
	insanely easy, use it and then any perl script would be Jabberized
 Transports:
	Another perl module, maybe Net::JabberTransport would provide the
	easy framework for building transports in perl

That's a configuration issue.  If you install a transport locally, you can
configure it to accept data from only local transports or from anywhere on
the net.  So yes, you can use someone elses AIM transport if they allow
it, *g*.

Couple of ideas here... I think I'll reply to the next message(since I'm
reading ahead ;) and touch on this topic...

An intro FAQ is an excellent idea, I'll whip one up soon here!

Any/all help is greatly appreciated!  There's a ton of power behind this
sucker, so the sooner we make it to the general market, the sooner it's
waves will be heard worldwide!  Fun!
