**Project proposal**: An IM client that synchronises seamlessly with a contact list stored in an enterprise social network system (think: MS Exchange (webdav?), Confluence).
**Initial thoughts**: Use Jabber
**Project Abstraction**: Generic notification mechanism which could be used to send email, SMS, IM. Useable by CruiseControl/DamageControl/Confluence/IM client etc.
**Rational**: Certainly a need for this at work. Is there desire enough to do it?
_Update_: Also think friendster/orkut integration. I’m thinking a server with modular contact discovery mechanism, with client abstraction. Suport for multiple IM protocols or just use Jabber? YAGNI – use Jabber. I should really stop engaging in design by blog.
_Update_: Look at Jain – “JSR 187(JSR 187: JAINTM Instant Messaging)”:http://www.jcp.org/en/jsr/detail?id=187.
