First off, I must say I'm extremely interested in a Bubba server, and the ease of use makes me want to go buy it right now if it weren't for one nagging detail; It doesn't have a Jabber Server installed.
If it could come with the latest and greatest versions of either OpenFire or ejabberd installed, with configuration options for enabling/disabling transports (MSN, ICQ, AOL, Yahoo! gateways), it'd be wonderful.

Potential use cases:
* Send MSN/ICQ/AOL/Yahoo!/XMPP alerts when something isn't quite right
* Store all your conversations/history on a central server somewhere that YOU control
* Automagic OpenID solution
* Your own IM server! (Coolness factor if naught else

* Lots of other potentially cool stuff...
Well, I hope you'll consider my suggestion. Good luck, and keep up the work.

Regards,
Wert
