Where I work (not CMU CS/RI), we run Novell, 3-Com 3+Share, OS/2 LAN Server 
and an IBM System/36 over the same UTP TRN (yes, simultanesouly) with very few 
problems.  There are over 90 nodes on one ring -- we use repeaters to keep 
the signal strong and filters on each end node.  The ring used to run over a 
distance covering 45+ stories, with no problems (we don't actively use that 
segment anymore).  

Our major problems come when a filter goes bad (usually someone moves their
machine, pulling the wires, making a loose connection).  This can create havoc
because a loose connection will generate lots of noise onto the LAN.  (The 
moral is to buy good quality filters -- and test each one before use.)

We're pleased with the results so far (been in a few years), and
we're adding a second UTP ring real soon now.
