I know I'm very late on this (sorry for taking a christmas vacation ;-) 
but how would I go about subcribing to a particular transition of a 
particular workflow?

This feels like the most common case for me, but it would seem that if 
you want to do that with the current patch, you'd have to have a generic 
subscriber that then if/then/else'd its way to only doing the right 
thing for the right workflow and the right transition.

I thought avoiding that kind of if/then/else'ing was what event 
subscribers were all about.

Hopefully I'm just missing something, could someone enlighten me?
(and by enlighten, I don't mean anything involving automotive fuel and 
matches :-P)

cheers,

Chris
