[FreeNX-kNX] Reduce nx/vnc bandwidth or other Screenshare method?

[Thomas Otto]

Hi,

now that my nx/vnc works I have throttled the local 100Mbit connection 
to ISDN speed using a tc wrapper <http://lartc.org/wondershaper/> and 
setting DOWN/UPLINK to 53 kbits.

At that speed an nx connection is still wonderfully useable, yet a 
vnc+nx connection to an an already running X session is not noticeably 
better than a plain vnc one.

One thing to improve this might be a colourreduction in vnc (as KDEs 
krdc is able to, vncviewer -LowColourLevel 0 somehow doesnt work) yet 
the nxclient doesnt seem to have this feature and I couldn't find an 
appropriate config option in the node.conf (via AGENT_EXTRA_OPTIONS* 
maybe?).

Apart from the vnc+nx way are there other possibilities to share a 
screen including mouse/keyboard in a low bandwidth environment? If 
nxclient itself could connect to the same virtual KDE session twice then 
I could start this kind of setup on top of a plain X everytime remote 
help is required.

Regards
