On Android you could accomplish this, but iOS has some fairly inane restrictions around running any type of VM. It's enforced somewhat arbitrarily, but it lets Apple yank any VM or app-hosting type thing on their whim. It was originally put into place to keep Adobe Flash and Air off iOS.

I also disagree that you always need mobile for everything. This seems geared toward communicating and collaborating, so yes mobile would be a must for mass adoption. But if it's geared toward devs or professional work that's not necessarily true.
