I wouldn't depend uponthe session IDs being unique forever. Even with IIS they are
only unique till you reboot the machine.

If you decide to roll your own ID, you are still going to have to hit the main table
to verify that the ID is unique, why not turn on auto-numbering for the main table,
insert there first - grab the auto-ID and then insert across all the other tables
using the captured auto number? Still two hits, less pain.
