We take a slightly different approach - and that is exactly what it is -
different - not better or worse.  In our case, we want our users working
in their virtual desktops all the time and the virtual desktops are all
accessed across the Internet.  Thus, we did not want users to have to
leave their virtual desktops to open another X2Go session in shadow
mode.  Instead, we placed "share desktop" and "View Another Desktop"
icons on their virtual desktops which use X11VNC to share the active
desktop.  Thus, all activity is from within the virtual desktops.

Since the VNC connection is inside the LAN (between virtual desktops),
the performance is very good and we gain the Internet boost from NX for
VNC just like we do for RDP when we push Terminal Server sessions
through NX.  Just another way for those with environments similar to
ours - John
