[Zope] configurating Zopes for merged logs

[Dennis Allison]

Yup, that is one of my fallback approachs.  It seems to me that I should
be able to write a configuration for the Zopes that either invokes a
remote syslogd server (or other server) which will merge multiple logging
entries into a single file on one of the machines in the cluster,
preferably the ZEO host.  Another approaches would be to maintain local
logs and then have a process running on the remote machine that performs
the merge.  We post-process the logs in nearly real-time and we expect 
related transactions to spread across multiple Zopes.
