There's a group called Antstream which has evidently been around for some time, though just opened a kickstarter campaign this week. They seem to be set on being a cloud gaming (Gaikai / Google Stadia) workalike, but for retro games that they are obtaining the licenses for.
The amount of computing power it takes to run these is trivial -- they are targeting 8 and 16-bit systems, and there's no architectural performance hit like in trying to do software emulation of a PS3 on x86-64 hardware. They could just as easily ship their own pre-configured emulator like any retro games compilation or the NES / SNES Classic Mini. Given that the emulator and rom should fit in a few megabytes, wouldn't any attempt to stream what could be emulated on a device just be wasteful?
