Doug, you didn't say what types of systems you are accessing via VNC.

If you are trying to remotely access a Linux box, you should do a remote
X-Window, tunneled thru ssh.   Its will be 5 to 10 times faster.

If you are trying to remotely access a Windows box, make sure you are
using "TightVNC" on the Win box.  Its a little smarter about updates
but all VNC over this type of link is painful.

There is also "rdesktop" as an option.

Thy empire come, thy OS never done, shipping as it is in development 

Give us this day, our daily bug And forgive address violations
as we forgive those viruses that trespass against us

Lead us not unto competition but deliver us from Choice
For thine is the license, the revenue and the greed forever. Amen
