[FreeNX-kNX] Using freenx to connect to a Windows Desktopserver (aka Terminalserver)

[Stefan Baur]

Hi Tobias,

while I haven't looked at the code, I'd guess that what it was *meant* 
to do is set $windows_app to the value of the *output* of the 
nxdesktop_helper script.

That would make sense in a way, say, running "iexplore.exe 
http://custom-url-passed-from-client" or opening an office document that 
has been downloaded on the Client in a Microsoft Office appication 
running on the Terminal Server, assuming the file location is somehow 
made available (and the path properly parsed) on the Terminal Server.

I've seen such beasts in commercial Terminal Server/Citrix environments.
