Extra Licenses needed for the S/W that VNC Server gives access to ?

[Mark Hill]

Dave;

I've set up a number of SCADA systems here in Western Canada. I use
eMation's Wizcon rather than Wonderware which I remotely access/control via
VNC.

The opinion around my shop is that only one copy of all software is actually
running. Even when we take control of the system via VNC, there is still
only one copy running.

If you'd like further info, drop me a personal note.

Regards
Mark Hill
