I guess. I've always heard FTS-1 and xmodem. Point is, this is the
minimum required for PSTN. Each PSTN mailer must support at least
this.

I have no idea. I wouldn't call binkp or telnet common in the respect
of "to every IP mailer", but they seem to be the most common used for
IP transfer of Fidonet mail.

It really doesn't matter to me what protocol is the minimum. The point
is that Fidonet needs a minimum required IP protocol for connecting
that each IP mailer can use. Other protocols can be implemented in the
mailers as well, but each would at least be able to do the minimum.
The next step would be to figure out how to negotiate the transfer
protocol upon connection. There is a conversation going on in
FTSC_PUBLIC about using a "finger daemon" to determine what protocols
are available at each connection and then starting the proper software
to use the protocol.
With a minimum IP protocol and a way to negotiate what protocol to
use, IP mailers would have the same "power" as PSTN mailers and
Fidonet could do away with the "I" flags. Simply list a flag to
indicate IP capabilities and the domain or IP address to use.
