I have looked at the arduino, but I prefer to have the general
linux computer available. With the rpi-b I get that for around $50, 
power, case, cabling and sd card. This one has ethernet, and they
really run reliably and well.

No, I want a rather full computer near the observation point, one that
can run autonomously in prinicple forever (in case there are issues
with management or connectivity) but can network reasonably well. 

This networking is pretty basic though. 

So the question remains, is there an IP driver for some of the builtin
stuff on the rpi0; except running ppp over the serial interface.
