I haven't had a single issue after making the switch.
What was happening before the switch:
Mouse keys turns on randomly when using VNC from Windows clients to connect to Vino on Ubuntu 8.04 Hardy Heron.
-and-
Periodically, my NumLock would turn off on Ubuntu and I had to physically turn it back on with the keyboard on the box (VNC never would allow NumLock to turn back on).
This was very annoying for me until someone mentioned replacing Vino with x11vnc:

Again, x11vnc fixed it completely.
