[Zope] configurating Zopes for merged logs

Zope 2.7.6 with ZEO Python 2.4.1 I would like to configure for a single merged log. If BE is the backend machine running ZEO and FEA FEB and FEC are various front-ends for the ZEO, what's the configuration supposed to look like to get a merged log collected on the machine on which ZEO runs. The only log I need to merge is the Z2.log--the othes can be left per-Zope frontend. While it would be nice if the merged entries were serialized, it is not strictly necessary. Cross machine transmission can be either UDP or TCP.
