Personally, I like the to KISS, so one big 'transit LAN'.

An argument could be made for individual VLANs to keep things like b- 
cast storms isolated.  But I think the additional complexity will  
cause more problems than it will solve.

Or maybe I'm just too dumb to keep up with the additional complexity. :)
