I think this is probably not the correct thing to do in general ... you 
could end up with the servers for the
X terminal being the same as servers for a unix machine which has its 
own display ... apps displaying on
both would share the same pasteboards and notifications, which doesn't 
seem right.

We could add a command line argument for gdnc and gpbs to start them 
with alternative service names, so you could
start a server for your windows machine on your unix machine

eg. 'gdnc -Host 172.20.36.46'

and modify the code to connect to it -

 if (_remote == nil &&  [host isEqual: @""] == NO)
        {
 	  NSLog(@"Unable to contact GDNC server on %@. Trying any host", 
host);
       _remote = RETAIN([NSConnection 
rootProxyForConnectionWithRegisteredName:
 	     [GDNC_SERVICE stringByAppendingFormat: @"-%@", host] host: 
@"*"]);
        }


Of course, the problem with this is that a host might have multiple 
names/addresses,
so when given the -Host argument, the gdnc server would need to register 
its
receive port with more than one name.
eg. GDNCServer-172.20.36.46, GDNCServer-WindozeXTerm etc.
