@Charles: Yeah there might be a market gap there. Having tiny audio/midi transceivers that take mic/line/midi and send things more or less directly to a tablet for recording seems kinda obvious - there's no need for large audio mixer - you could simply have a tablet with a screen showing each mic with a panelist name attached and solo the channels or whatever and have a bunch of plugins do any dsp needed. I suspect this might already exist on market if one really googled hard enough.
