Ah, thanks for the idea. SimpleIPC should be able to do the trick -
similar to how apps communicate to a DebugServer (using dbugintf and
SimpleIPC units).

First instance will search for a known IPC server, if none exist, start
the Simple IPC server. Second instance will first see if a existing IPC
server exists, and if so, send the open command to it, then quit.

That should work in a cross-platform way too.
