We seem to be ok with #4 so far, but we'll see. They'd be buying us for our technology and staff, we've gone really far where they want to go and I've had an intimation that they've put some R&D into it already and figured out that it's pretty complex stuff to do well. It's been an honor to have so many great responses, I'll post back here with an update (some weeks from now.. Christmas is going to be nerve-wracking unless Big Company really just wants to get this done before the end of the tax year).
