I recall using an app way back when I used to root and haxor all the mobiles that would do this. Kind of a virtualbox for the Nexus phones/tablets, but it needed root to do it. Will have to look into this, would be interesting if it can do so in user space somehow.
Edit: Damn, still needs root. Was a longshot to be able to hook into system resources without it but was hoping for some bridge function.
Not in a way that I've really followed up on after, but bringing up the next 'class' in the sense of giving the new folks those tricks that are not in the books and letting them take over where you left off happens a lot in my work. I suspect people do so more than they know every day though. Sometimes all it takes is to sell someone on the idea that they can do the thing that they're not so sure of.
I do know I've been on the receiving end of it though.
