Actually, for supposedly "not knowing what you're talking about" you make a fair amount of sense.

We've thought about how you'd go about developing the different applications all based on the same engine; we've played with the idea of just laying out all the possible applications, and then saying, "Hey, anyone want to work on these," and then build our team bigger and see where it goes. That's probably the route we'd take if we were interested in open sourcing it.
You comments about open sourcing the engine but not the results is interesting, and something I hadn't thought of myself. I'll have to think about that a bit.
Ultimately, as much as I love open source movements (and Paul and Brandon are far bigger fans than I), it'd still be nice be able to pay for my bread and water with this project - Open Source makes that a bit more difficult, though it has its ups as well.
