Queen of the Sky Multi-Crew Multiplayer SC

[CargoSwiss]

Greetings,

Group of 747 enthusiasts is setting up Multi-Crew operations for the PMDG 747.
Anyone with experience out there on Multiplayer?
Until "SharedFlight" will be released, what technology exists to get a true shared cockpit to work on a single flight deck to include also instructor station to effectively simulate a fix-based trainer device?

We have a 747 Discord for PMDG, PSX, SSG and alike - trying to get Multi-Crew ops going, including performing flows, checklists, taxi/departure briefings, arrival briefings and so on.

Appreciate any pointers re what capabilities exist to unlock or plug-in to P3D. Thank you and Happy Landings
