I'm currently building a livecoding environment with two BELA boards to which I connect from my main computer via WLAN. My chosen Platform is SuperCollider.
If you're interested in the conceptual part, read on here.
Part of this is that I started implementing a ruby script to control multiple BELAs form my main machine (set time, start/stop IDE, start scsynth etc). If you're interested in this, get the sources here. The base repository will eventually fill up with my other remote-livecoding-related material so stay tuned.
