We have performance and reliability expectations which come from running
mission-critical applications.  Lots of the rest of the folks interested
in servers don't have those requirements (yet, anyway), and hence aren't
motivated to address them in their externally-maintained server
implmentations.

What is *worse* than maintaining our own server is trying to track
development on somebody else's, where their goals don't match ours.  I'm
guessing that the amount of effort required to "maintain" the Zope2
server per month is less than the aggregate time spent by the community
reading this thread. ;)
