Eric,

>Hold on here, lets figure out what kind of state we're trying to preserve. If all you are trying to do is prevent an update conflict, this can be handled with a timestamp.

Thanks for the reality check, and suggestions. I can't speak for Jeff's particular needs, and I'm only part-way through my usual "mulling-it-over" process of decision-making/ brain-storming on this part of the project design.

I've got an all-nighter ahead, so I'll mull a little bit more before posting a followup... more later. Thanks.
