Yes, this is roughly how a hurdish network stack has been envisioned
in the past.

Shouldn't it be /eth0/ip/tcp/?  I.e. with internet protocol is layered
over ethernet.  Though it might be that I have misunderstood your
example or the protocol stack in general (this is not my area of
expertise).

In any case, I'm not sure why you have chosen directories.  Why not
just: eth0, eth1, ip0, ip1, tcp0, tcp1, tcp0+1 etc. where tcp0+1
works like your /ip/tcp/?
