Yes, I am missing some point.  If you run X you can run anything from 
anywhere else in a window pretty much transparently.  Why can't you add 
accounts for everyone on the RH 6.1 box (probably doing authentication 
against your windows domain since everyone with exchange mail must have 
an account there already), maintain the exchange connector there and 
give everyone a launcher that will open it on their desktop?  You can 
get the effect with 'ssh -Y remote_host thunderbird' from an open 
terminal window without any other setup, but you'd probably want to give 
others a nice launcher and you may or may not need the ssh layer.  As a 
side effect you get shared-memory efficiency for every instance of the 
application running on the same server.

If you want something slightly more extreme, you could build freenx for 
the RH box and run whole desktops there although I don't know how many 
users you can put on one box unless most of their apps are remote. 
Personally I prefer NX/freenx to using a local console but that doesn't 
change your ability to also have applications remote from the desktop.
