Don't know about novell.  I do know that Cisco Routers support Novell
Routing (and bridging), and that novell routing traffic is monitered
in general, but not port by port.  If you had a cisco at each location, 
you could monitor the through traffic and locate load.

Cisco's Novell routing works well from what I've seen.  It works like
the servers, you address each net uniquely, and it advertises and sets
up the net with the servers.  It is not a bridge and will save you
lots of bandwidth in the setup you propose in traffic isolation.

One thing though.  Remote server access across a T1 is slow.  I recently
spent time at our remote site and did software development over our 1/2 T1
link.  It was not quick by any stretch of the imagination.

From what I saw using 760K bps, 56K would be painful.  19.2K would be out of
the question.  I hope the leased line connection in you diagram is Digital.
Otherwise, you are going to hate what you get.


Have fun
