All those are viable alternatives.  Serial (i.e. out the modem/printer
port) would probably end up being tethered with a shorter max-cable
length.  Ethernet with an Uther card (another run is in the works) or
a Gatorbox would likely be more expensive.  Either way, you'd need to
cook up a thrower/catcher software arrangement between the GS and the
"other" box with a protocol wrapper.  I can imagine a system where
data were buffered during periods of non-connection, and
acknowledgments would clear out the buffered data.

I suppose writing a Contiki app would be a possibility, with more
conventional TCP/IP protocols/data transfer mechanisms within easy
reach.

It would be a fun programming exercise whichever way you ended up
going... it all kind of depends on what equipment you have on hand or
want to invest in, plus what kind of software development work you
want to do.
