Only issue with syslog is defining what facility to use and changing the code to use it.

It's the Unix standard to run daemons in low-numbered ports, and we know the reasons for it. I'd propose calling socket() and then setuid() (with the relevant save pid step), and then run the ZEO normally as the user using either a user-written log or syslog. > (I have cc'ed zope-dev. I suggest we continue there, rather than zodb-dev) This is really a ZEO issue, as far as both Zope and standalone ZEO's affected, but anyway..
