It looks as though there is some amount of ENC28J60 IP stack for Arduino 
already existing. The thread on Adafruit refers to a V6 implementation on 
Arduino. Have you taken a look? It is ported from Contiki, so it is already 
more or less familiar and you should be able to form an educated opinion on if 
it has any value for us. Basically it boils down to two questions:

Is the Contiki IP api abstraction good for us?

Is the Arduino port full of 8bit quackiness, or could it be easily ported for 
32bit Arduino/ARM?


Now, this would be V6 and for our first tries at a local isolated island 
Ethernet I’m not the slightest bit interested if we’re at V4, V6 or both. The 
aggregate node on Raspberry Pi can perfectly well translate anything to real 
world V4 as soon as we need communications to outer world, as with the Results 
Day demo.

For those asking why V6 first, we could answer that we decided to start from 
the future and add support for the present moment only later on…
