2 screens

OK so I have a linux box and 2 mac laptops on my desk. I use the linux server via KDE or gnome over VNC. This works quite well. However what I want to know is this. I have 2 monitors and can in theory have 2 vnc sessions on them. Is there a way to have the same gnome or kde session on both vnc sessions, so I can look at different virtual screens.
