Finally, some interesting observations from the Martillo side of the
recent "martillo vs the world" debate.  Let me try a reply:

I think I agree.  Note, though, that there are several different
product spaces.  I expect to have 100Mb rates on my campus backbone in
2 years, but will be lucky if I have telephone lines into every student
dorm room; if I *do* have telephone lines, it is unlikely that we will
be able to afford anything faster than 2B+D ISDN.  A fortiori, I don't
expect to see data rates to mobile stations (e.g. portable PCs in
cars.  Rates to/from tanks will obviously be much higher) of much above
9600b for a decade.  So I *do* care about having a network windowing 
technology that works well over slow links!

There are different kinds of context switching, obviously, with different
overheads.  That's the whole point of the lightweight-process argument.
Martillo's argument would be stronger if he could demonstrate that
the "contexts" necessary in a NeWS server were actually fairly heavyweight.
