	Yes, the token ring works just like the Ethernet as far as X is
concerned.  However, you should be careful about choosing between the domain
ring and ethernet approaches.  Domain ring is supposed to be faster (we
don't see any appreciable difference) and has been supported by Apollo for
a long time so is likely to have been tested better.  However, ethernet is
nice and standard-- etherfind, protocol analyzers, bridges, terminal servers,
and many other things work on ethernet since it is more widely used.  We
run domain-ring, but I would rather be running ethernet so that we could
use more of the tools we have around here.  

	Also, since there are problems with SR9.7 and the gateway code,
you should probably run SR10.1 (which is rumored to be shipping RSN).  The
problem here is that X isn't available from Apollo for SR10.1 yet and probably
wont be until April or so.  The MIT distribution is kind of clunky on the
Apollos too.  If you are buying nodes in the near future you may have to wait a
while to really get X usage out of them, but Apollo has promised that they
will deliver.  Another issue is that I'm not sure what version of X Apollo
will be shipping.  The SR9.7 version is V11R2, I don't know about the SR10.1
version.
