Note that what you're describing isn't really part of ZEO, it's really more in the realm of what is already in Zope. Thus, if you're eager to add such a feature, you already have what you need. Start tinkering with the transaction machinery and see how you can extend it. --Paul

Some sort of transaction log would be nice. Not only could you track this to do replication, it would then possible to rebuild corrupted Data.fs files as well. I don't know if ZEO already does this, this is just idle speculation on my part.

I guessed as much :-)
