@Kamoflarj,
It looks like the PMDG 737 only supports shared cockpit through third party addons, such as the below, but I believe it is possible:
http://www.desk-pilot.com/#I also don't have the PMDG 737, but if you have alternate aircraft ideas, let us know. I personally would love to try out Carenado's B200 King Air in shared cockpit mode.
@Paul/Fozzer/Cessna 150 guru,
I'll take note of that server for our future flights. Additionally, I'll see about coordinating two flights, one to occur Friday evening my time, which is midday the next day in NZ, and another midday Saturday my time, which is evening in Europe on the same day.
EDIT:
Adding to the above, keep the discussion going. Aiming for maybe a mid or end of September event if possible, but we'll have to work out all of the logistics.
