comes quite in handy when you have a spare pi lying around 8-)
so I built the pi version of the gateway.
Now I can see both the plugin version and the lib version in the plugin device on Vera.
Alas, there seems to be the same problem with inclusion mode.
Additionally, gw and sensor seem to be unable to communicate.
When I restart the sensor node this is it's debug output

On the gw side I did the test as suggested, output looked exactly as it should.
When I tried to look at the debug output again I only got
mysgw: accept: Bad file descriptor
I then tried the alternate wiring using the interrupt pin and reconfigured, same result.
