yes, that would be nice. I'll include this into the 'getting started' guide.

that's a good question. The TouchPerceptor for example does send 'val 0'
while no collision is detected. So this perceptor does send data when no
collision is detected.

We should decide for one behavior for all sensors. I'd say where
possible keep silence (saving bandwith...)

I agree that using degrees/sec might be more convenient. But changing 
this causes trouble for existing agent implementations as they still 
expect rads/sec, so their agent implementation fails silently (i.e. 
without an obvious error).

To change this we must also change the message format of the effector to 
make it clear that degrees/sec are expected and still support the 
current message format. I don't know if this is worth the trouble though...
