Route Data from OpenCPN

[PaddyB]

Are you able to get a Rhumbline on the second OCPN instance? Or use those sentences in any way - project a destination waypoint for instance?

It's the same route so activate it on any machine and everything is the same. If you want the rmb etc sentences in SignalK then just output from one machine.
Resilio sync is good to keep files synced across devices but folders only unless you pay for the full version so you still need to manually copy across the navobj.xml files on each machine which is a bit dull but you can write macros in node red on linux or automate on android to do that. Resilio is sort of like a local dropbox.
