Thanks for the reply, Tom. I was thinking I could have my remote
process send a message back to PG via XMLBlaster, too. XMLBlaster is
a MOM-like message-queuing app that guarantees delivery to
subscribers. (www.xmlblaster.org). The problem, as you stated,
though, is transactional integrity :-(. Hmmm, I'll see about the
to-do queue idea.

Thanks again for your time!
