the best case latency in the camera stream is around 300 ms, however the latency in the control stream is much better ~20 ms, so it can be used with higher speed than 1 km/h
In default AP mode the WiFi network is created around the 15th second after startup, but note the smartphone should be also connected to this network and it takes time too. By the way you are right, the kernel boot time is about 5..6 sec, and the WiFi AP creation takes further 8-10 sec (maybe this network creation can be polished).
WiRC stands for WiFi RC
The method we send the protocol specification is a bit embarrassing but we just would like to see how many people are interested in it (and see the possible usage scenarios). However currently we have got so many requests that it seems it would be better to make the specification downloadable on the website.
We are happy to hear that WiRC made it to slashdot. By the way if the "anonymous reader" would be us (Dension), then we would linked the official website instead of an Italian site, especially since we are located in Hungary
