You're welcome. Just be careful with Ejabberd that external services do 
not work as intended (at least in the previous versions and I don't know 
if they manage to do something about). For that I used exmpp which works 
like a charm and it's very simple. In my project (something similar with 
your's) I used YAWS (Erlang/OTP web server) which allowed me exmpp 
instances without too much of a trouble (both being written in Erlang/OTP).

Another option (even simpler) is CouchDB which works great for blogging, 
but it can simulate pretty easily a messenger. CouchDB is Erlang/OTP and 
JavaScript. The main disadvantage is that it doesn't follow any 
messaging standard.

Good luck!
CGS
