Amoeba on a token ring would be difficult.  Amoeba transaction protocol
(TP) relies on (bletch) broadcast to locate an Amoeba service (actually a 
port) on the network.  On an ethernet this will work, though you get 
problems you have lots of amoeba nodes chattering away.

Token rings (and slotted rings) do not support physical broadcasts.  This 
is ONE of the reasons that Amoeba TP is unpopular around here.  A few
months ago I was talking to CWI people about a broadcast-less version 
of TP, but that project got put to one side.
