Many thanks Greg.  If I understand you correctly, the round trip time
for interactive use would be about 300 milliseconds.  That would be
quite consistent with what I have read here (some people complain and
some do not).  I think I remember there were some IBM System
Journal articles long ago that indicated that programmer productivity
was impacted if system response time was greater than 200-250
milliseconds.
