Larry,
Thanks for the advice. I didn't think there was a way to do this in a
"loosely-coupled" system but I thought I'd ask. I believe that I can rely on
HAT to be able to resubmit if any of the three transmissions fail and not
worry about the three systems being out-of-sync for a short time period.
