Just pulling this out of my "you know where..."
BUT, what about if you had a BO with 2 fields. ID and Tennant #.
Prior to calling jasper you add a record to this table with the T#, then retrieve the ID. Pass this ID to Jasper, it can look up the T# and then, you delete this record. So even if someone was "sniffing" and saw the ID, it would be useless to them.
(of course, instead of ID, you can have a random # or ???)
