I'd be curious to hear those anecdotes. Where I work, we use zsyncer daily
and we *always* use ZEO.
The only potential issue I could see is that ZEO adds some network
overhead to ZODB writes, increasing the chances of a conflict error
(or, in recent versions of zsyncer, a timeout).

We synced from 2.7.X to 2.6.X for quite a while with no observed
problems. (Our development systems are often more current than our
production systems.) Never tried the other way around AFAIK.

... which, just so you know, is now different enough from the current
codebase that if you had any problems with it, I'd be unable to give
you any advice except to upgrade :-)
