The idea sounds highly bogus. PPP is a way of adding packetization and
content types to a serial link. Ethernet has both already. Besides,
PPP is a point to point thing, an ethernet is a bus.

I guess the poster wants to connect two ethernet cards directly to
each other using a crossover cable. This could save the ethernet
overhead. Plus it would probably make for easier bonding of multiple
paralell links. Could be interesting...

could you explain how ppp encapsulating (etherh+payload)
reduces the overhead?

buy a 100mb ether card.

Who says you need the etherheader? Its not ethernet, its a point to
point connection in this setup.

Of course one would do this with 100mb ether cards.

I can think of applications where bonding wireless interfaces could be
useful..

Wouldn't this be a way to tunnel IP in IP over ethernet?

If you are using ethernet cards to talk to each other, it _is_ ethernet.
The bits will be placed on the wire, the framing, CSMA/CD algorithm etc,
will all be done in accordance with the 802.3 spec. The physical wire
will be carrying the bits in 802.3 format, including the preamble,
starting frame delimiter, MAC destination addrress and MAC source address,
since the cards don't know how to use any other method of framing and
sending the data.

Nah, They never heard of virtual circuits.

Seriously, PPP over IP is a way of building a cheap VPN. The thing is that
SSH already does that job much better.
