Dispatchers didn't talk to each other?

If you know who's going where from your airport, and the (NetJet)
dispatchers from the other airports know who's going where from their
respective airports, much could be inferred by putting the info together.

That's not the way the system is set up.
All NetJet pilots in North America talk to NetJet dispatchers in the
North American operations center.
Nowadays, the dispatchers are grouped by aircraft type/fleet (Citation
X's, Falcon 2000's, Citation Excel's, etc.).
Back when I did it, NetJets had less than 100 aircraft (Citation IIS's,
Citation III's, Hawker 1000's). The day and night shifts were each
staffed by three dispatchers and a supervisor. Graveyard shift had only
one dispatcher.
We all had access to any aircraft's information.
The crew used to contact operations via telephone for a release and
trip/pax information prior to departure and again upon landing with
flight numbers . Now they communicate via Blackberry's.
There are separate operations centers for Europe and the Middle East.
