Oh my, yes. I had forgotten that Steam streaming was live now.

But that's just Steam. Expand that to everything in a couple of years, and you're there. Maybe Valve could get into that business themselves.

Yeah, it's technically here with media servers too but the barrier for entry is still higher than your average Joe will bear. The idea of an out-of-the-box solution has been tossed around here a few times I think; a little server that manages networking, storage and other services for your home. One that just works after a simple gui walkthrough for setup, and doesn't make us so dependent on cloud services that exist to sell advertising space.
