or disadvantages of keeping the ckts each in their own
individual LANs or tying them all into one VLAN for a
"Transit LAN" as those folks that decided on going to Gig-E
aren't doing any logical network architecting (is that a
real word?).

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. :)
