I just popped a plugin target to Adium’s trunk that will linkify the trac’s shorthand for changesets and tickets.  It’s still a bit janky, and not at all supported, but it makes things a bit easier when talking about tickets and the like.

It’s mostly recycled code from AutoHyperlinks, and for now it only supports Adium’s Trac.  However, if you find yourself working on or talking about Adium code a lot, you can find it here: Developer Links Plugin.

Eventually, it’ll have a preferences GUI so you can bind it to your own project management system - even several.  But for now, it just works for Adium.
