Right, something a little like that. Like I described in a different
thread, I found out, that adding a timestamp to each record doesn't
work in case of overlapping transactions.
I thought about the approach using the OAT a while and found out, it
leaves me with the same problem.
I guess I'll have to use the approach Adam pointed me to in the other
thread - using an "updated records" table for each subscriber.

Thanks
