I am one of the other people RJ is talking about. I too looked into such a design after the idea was bandied about here on DLA. I suggested it to RJ and volunteered to design it. He said that he already had a similar idea in the works, so that was fine. No need for me to re-invent that wheel; there are many more wheels to design.
For my other projects (the tester, servo controller, and pixelnet splitter), I checked with RJ before turning them into real projects, and he was fine with them. He even helped with the tester by creating a modified version of the wireless firmware.
It's real simple - DLA is RJ's "house", so we go by his rules. I am glad that he lets me play along...
