I use ZRS ... I can't report much since it seems to have worked fairly transparently so far (A good thing!). 1 Master + 1 Slave ... When one of the boxes goes down for a reboot/maintenance, service is uninterrupted, since it supports a 99% read web site, I haven't had to work too hard on read/write performance optimization ... We also use a combination of heartbeat + drbd (http://www.drbd.org/) for some filesystem based replication ... Our PostgreSQL server is made highly available that way. In retrospect, I could possibly make the ZEO server highly available that way I think ... I can't say much about the drbd setup since I haven't worked on it. Our corporate IT team takes care of that for me. I take care of our ZRS setup however.

Is anyone familiar with the heartbeat, fake or ultramonkey tools? I'm just starting to look at these now and wanted to see what the experience of others was. I assume this is fairly common with Zope and Plone installations.
