Proprietary...not sure I remember that term :^)  The zope.org RSS is
21.5 Mb.  I'm not sure whether to think this is good or bad...we upload
all the distributions and PDF files into the database.

Anyway, this is a *very* good conversation to be having.  Our newspaper
folks had 80+ newspapers, each running two processes.  It was on a
64-bit machine (Digital Unix), meaning everything took more memory.  We
had to work hard to keep the processes at an average of 15 Mb.  Thus,
doing the math, we were talking about 2.4 Gb of total memory consumed. 
Needless to say, we tried to encourage them to run several papers in one
process.

So Zope needs to be able to host 100+ "virtual hosts".  If the direction
is doing them as separate processes/installations, then every little bit
helps.

This is a perfect job for open source.  There are folks on this list
with a lot of talent at looking at these kinds of things and running
tools and tests to see what happens.
