Sounds interesting, indeed. How about USB redirection, is that possible
in any way? (things like flatbed scanners etc.)

I was told from the makers of ThinLinc that scanner information is
difficult to tunnel and that this is not implemented yet, but on my IGEL
UD-series client's custom partitions I have the SANE libs and daemon
installed that correspond to the versions of the server's Debian Wheezy
installation. With these it is easy to scan over the LAN, albeit
unencrypted. gscan2pdf is your friend. A bold test of WAN scanning (just
for the fun of it) failed, perhaps I did not open all necessary firewall
ports or lost packages were the problem.

The SANE network protocol is unfortunately not very firewall friendly. One "solution" (in addition to using a hardware based USB redirection) is to scan locally but redirect the output image to a directory which has been exported to ThinLinc session (what we call "Local Drives"). This approach is setup by default in our "TLCOS". If you press F8 while logged in, you have an option "Start image scan". This is a limited solution though since all scan options and parameters must be set locally.

Btw, if anybody feels that I'm talking too much about ThinLinc on this list, please say so. I don't want to be too much off topic :-)
