Many things on ethernet together???

[Bob Toxen]

You can run just about any protocl on the same ethernet cable.
This is because anyone wanting to devise a new protocol is supposed
to obtain a protocol number from Xerox.  This protocol number is
encoded in the sent packet.  Receivers are expected to recognize only
the protocols they are prepared to deal with.  This is why this works.
