[Feature Request] Cross node connectivity

[mertensm72]

I would like to use one BBS with two nodes: one 868 and one 433
My idea is to send BBS mails between different networks.
So the BBS has to remember the origin of each Node...

+1 to this, I would like to have the same BBS available on longfast/mediumfast/verylongslow

If you have multiple radios plugged in on different serial ports I think you could run multiple instances of the python server all connecting to the same sqllite db?

I don't have multiple radios, but if you do it should be simple to test if I'm understanding the code base:
In one terminal run python server.py --interface-type serial --port $LongFastPort
In another terminal run python server.py --interface-type serial --port $MediumFastPort

If it doesn't work, I would guess it to likely be a locking issue somewhere.
