I certainly envision networks of ethernet, fast ethernet, and eventually
gigabit ethernet as opposed to FDDI or the like.  The interfaces are
generally cheaper, and I think people are more comfortable with ethernet
and ethernet-like technology than they are with FDDI, etc.  The networks 
we build here are entirely ethernet and fast ethernet based.
