Yes.

I just meant protocols used for FidoNet mail transfer.

I understand there is ifcico but I haven't looked at it yet, but from what
I understand it's basically just FTS-1 over IP.  Which has me wondering
what makes it any different to running a mailer using VMODEM or equivalent.
 I guess I'd better take a look at it.

Well, I mention BinkP because it's by far the most common.  Plus you can
actually send mail with it.  ;-)

Yes.

This can be done manually until such time that the software can negotiate
automatically.
