 SP> Guys, do you read what you post?

yes... with an open mind, too ;)

 SP> There is no mention of incoming connection via binkp.

there is no distinction made on the protocol or connection method... it says
"any system which wishes to be part of fidonet"... the key part is that
systems should be contactable for at least one hour a day so as to ensure that
other systems can deliver mail to them... that's the whole point of ZMH...
that a system is CM (Continuous Mail) is ok... it is a greater capacity than
the requirement of ZMH but systems that only operate during ZMH must also be
able to deliver mail to other systems... it isn't rocket science... not all
systems run all the time... ZMH simply guarantees that there is a time when
systems can deliver or pick up mail and all fidonet systems must support
ZMH... protocols and connection methods don't matter in this case...

consider systems connecting via shortwave radio links...
consider systems connecting via postal mail (eg: tapes of mail)...
consider systems connecting from extremely remote locations where there is no
internet, wifi, or POTS...

correct...

that's all it discusses because that's all there was at that point in time...
"tunneling" via ftp thru what would later become the internet was also used
but it required specific agreements on both ends for use (eg: time use, data
bytes) so only a few systems used it... the main use of ftp for fidonet was to
connect the zones together... then there is section H. ;)

i won't mention FTN over telnet or vmodem but they do allow for FTS-0001
comms... but these are still available over other physical layers than the
various telco plant spread all over the world... did you know that telco's
lease time on the electric companies' fiber networks that physically resides
inside high voltage distribution cables?

what would be the physical layer for a light wave connection?

that is the latest version, yes...
