Alpha 2 doesn't change anything about this. I believe we still have yet another take on the hosting APIs which we're still going to do and we'll probably resolve that issue then. I'll make a note to send out a mail once we've made that decision (and it'll probably be release note worthy as well).

Hi Dino, Congrats on the new release! Can you give us an update on the status of the multiple engine debate and does this release change anything on that front? When Alpha 1 was released, we discussed swappable SystemStates as an alternative to multiple engine instances. Does this release include this functionality?
