[wp-hackers] automatically trackbacking a url if post is in given category

[Tara Star]

This was a neat feature of MT that I haven't found in WP (maybe I 
overlooked it).

e.g., each time I post something to my "Music" category, I would like WP 
to trackback http://topicexchange.com/t/music/ -- can that be done? Does 
a plugin/hack for this exist? (otherwise I'll end up doing it if nobody 
does ;-))

Trackback to http://topicexchange/t/wordpress/ if you post about WP!
