No direct experience ..

However, my understanding is that it is not all-or-nothing.

For most apps, they run on the server, display on the client -
regular LTSP style.

However, you can pick certain local apps (a browser comes to mind)
that run locally (invoked by rsh, a very insecure remote shell
protocol) but talk to your window manager (on the server) and
then to the local display.

It is just as easy (and quick?) to run a browser on /some other/
client computer for your own purpose.

The 'icon' or whatever (on the server desktop) would execute :-

rsh <bobs computer over there> netscape -display $DISPLAY

or something similar.

Corrections welcomed.

Cheers,    Andy!
