After brion's bug 27147 comment 3; Either server side or client side.
JS:
The links would be given a class around: http://svn.wikimedia.org/viewvc/mediawiki/trunk/tools/bugzilla/bugzilla-4.0/extensions/Wikimedia/Extension.pm?revision=84488&view=markup#l66 and a call to the mw.org api would get the status.
Serverside:
A way to query the database or api from there serverwise and put it directly in the output.
