Yes, at the click of a button. We've demostrated that already elsewhere - it works nicely. 

And yea, hosting. But, to make a long story very short: the market will handle that. Our computational model quite well suited to something like a bidding-based resource hosting market (or you could always pay a more traditional VPS service and run there, again at the click of a button. Or host it off an old laptop or pi in your closet. Or all of the above if you're a fan of lots of fail over redundancy) 

 Then let's go! Let's make it accessible via one-click setup a relay on something computationally cheap.
