Brian,

Thanks for replying. I've been in touch with Mark regarding the VNC
remote sessions, and am for now playing with Xdmx as a proxy, with X11
remote clients (and Xvnc now I've got a workaround patch for the crash.)

Unfortunately, as Xdmx uses XLib for its "screens", as soon as you
terminate the network connection to the thin client machine, Xdmx will
quit with an XIOError. (XLib kindly calls exit(1) for us). This will
need some work to XLib to over-come, which Mark tells me has been looked
at before.

For now, the Xdmx proxy seems to work, and is hopefully increasing
speed. (I've yet to try it from a less featured X11 server such as I had
speed issues with before).

If I come up with anything useful, I'll post it back here.

Kind regards,
