[ZODB-Dev] Undo differences between Z2 and Z3

There seems to be enough of a difference between Z2 and Z3 undo to have an effect on a backend like PGStorage from working on Z3. I believe the objective in the storage api is that it should not matter to the backend whether you are connected to Z2 or Z3. Can someone more familiar with the

[ZODB-Dev] ZEO Authentication

Well, you might need a few monkeys for sure :-) I guess it is safe to say, that the authentication built into ZEO is not used extensively. You never know until you ask. I guess if it were, it might depend on the use case you have for ZEO more than anything. Many thanks. Regards David You
