Are you asking at the ZODB level, or at a higher level, such as Zope? We use it in our Zope 3 based CMS. We usually only expose a single-level undo and have not exposed any interface to undo more. I have noticed that trying to access the Rotterdam skin (I guess) "undo more / undo all" views blow up when using ZEO. But again, we don't expose those to our customers and never really use them much ourselves. All we use is some of the APIs from `zope.app.undo` (v3.4.0). The closest we get to interacting with ZODB level code directly is setting extended info on a transaction, basically to make a smarter kind of 'undo last' action.
