Wouldn't mind c0ff or Chizh, just to get the nuts and bolts architecture of DCS, and maybe how it has evolved over time from Flanker (if Chizh was around back then)
Also the vision for the future DCS architecture. I see hints of a general Server/Client model being pursued, but overall it'd be nice to know a bit of technical detail as to how it all hooks together (not that I'm at all technical when it comers to programming).
