Speaking from the Zope2/Plone crowd: I'm using it during development with a local file storage at times. In a real ZEO production setup, undo in Plone most of the time only works for a quick: "revert the last transaction". For any transaction that happened a while ago our catalog-overuse will cause some persistent object inside the catalog to have changed in a later transaction. Throwing away all changes done in the meantime is usually not practical. For recovery purposes of older data, we have found a bit of manual work and zc.beforestorage to be the better approach. So if undo is gone from ZEO it wouldn't be tragic. If the "remove last transaction" could be retained, that would be nice.
