Re: Pipping android to the post
Nope, it's already available on Android, has been for a while. It's just on tablets and not phones, though- I think Nokia or someone have an old patent that they wanted to avoid.
A colleague brought in her Nexus 10 for me to play with, yesterday, as it goes. I made an account on there, and installed some of my own apps under it, it all worked really nicely. Once I was done playing, we went back to her account and nuked mine, freeing up space. It was all very slick and useful.
I suspect BB's talking about something more along the lines of those managed containers that VMWare and co use, where the business stuff is all nicely encrypted, and remotely managed by policies- not sure that Android does all of that yet, at least not the second bit. The idea there being that the IT dept could set expiry on stuff, lock it as needed (well, I am sure you get the idea, I won't insult your intelligence by over-explaining).
