Well this is slightly tricky. Normally rsh may not even pass the DISPLAY
variable to the remote host at all unless you explicitly set it. I am
not familiar with qrsh. As for the hostname, you could probably tweak
one of the nx scripts to do this. Of course, this would mean that
locally invoked clients would then use tcp instead of unix sockets to
connect to the X server, which could be slower.

Either way will involve a bit of hacking. On my system I have a special
script used for invoking applications. It looks up a database to find
out what host the command should be run on, mangles the DISPLAY variable
as required and then runs the command with rsh.
