Yes. But my DA a bit simpler: single user per single Zope session per single 
Oracle session. To get this, I use lock's. This means, that you can not get 
the same uncommitted connection untill it is committed or aborted. This works 
exactly as Oracle Forms does: untill you save and commit the transaction (or 
reject/abort) you will not be able to do something else. 

Well, not that multitasking :-) but at least works as stable as a rock. Maybe 
I still something missed yet. If yes, would be very nice to get it know...
