Even the standard version of VNC from realvnc.com does this already,
and uses a reasonably small encoding. I find RealVNC over my 100Kbps
IPsec-over-DSL VPN to be perfectly adequate for most things. TightVNC
uses a much more aggressive (and lossy) compression
algorithm. Personally, I find TightVNC to be barely-usable, because
the display artifacts resulting from the lossy compression are
distracting to me. OTOH it does make VNC connections over 24K dialup
links "barely-usable" rather than "completely unbearable".

Another problem I've had with TightVNC is that it uses up enough
CPU time (on an 800Mhz P3) to significantly affect the timing
characteristics of other apps running on the system.

(It may sound like I'm dissing VNC, but I use it all the time,
and I mostly like it just fine. When you use *anything* a lot,
the flaws start to bug you more.)
