[GE users] Mapping of usernames that differ between submit and exec hosts?

Ben - I've never seen anything like this in SGE - as a matter of
fact, page 94 of the SGE SysAdmin manual says:

"To submit jobs from host A for execution on host B, users must have identical
accounts on both hosts. The accounts must have identical user names."

I can't think of any way offhand to get around this.
(I'll refrain from commenting on systems that have different names
  but use the same uid... ;) )
