Related, I was thinking about things along the same lines.  One thought 
I've had in the back of my mind was to have a wee Shivaplug or similar 
device attached directly to each L3 router, into which the L2 vlans can be 
trunked, and it can collate the info for central gathering.  (The actual 
application I had in mind was as a remote 'test point' for network 
monitoring and possibly network sniffer for those ad hoc times you 
sometimes wish you had one when you are far away from a place with 
something going on).
