It's nice to fantasize about this, and the cool part is that tech is moving so fast that stuff like that (not to mention real-world simulators, etc) will inevitably surface at some point. For now, though, I continue to be excited at what the US staff provides us with (been using it since v1), and hope they will (at least with US2) not stray too far from the main objective, but commit to fully developing what promises to be the ultimate space physics lab software, the benchmark for all future attempts. (Edit: I say this knowing little about the software NASA & co uses, I'm sure it's advanced; I was referring to more layman-friendly approaches that can please scholar and dabblers alike.)
That said, I'm with you on the exciting prospect of future technology & processing power.
