  Maybe.   I know that AX.25 has a protocol ID byte that specifies the packet
type being piggybacked - I'm pretty sure IP is 0xCC.   It might be that
someone has already implemented a DECnet payload, but it's a long shot. 

  I doubt it.   We could, though.

  We could build our own TNCs that spoke 1200/9600 baud AX.25 on one side
and DDCMP on the other.   All it really takes is some firmware... That'd be a
really cool gizmo, and completely useless to anyone except for a couple of
people to boot :-)

  I would LOVE to do that.   That sounds like great gobs of fun.

  Realistically, a smarter thing might be to try WiFi.   I think the current
distance record for WiFi is something like 250 miles; how far is between you
and Steve??   Of course, you'll need some pretty tall towers...

  I don't know specifically where he is, but I think he's east of me.
There are mountains...that'd be tough.
