Do you think it would be viable using a pool of 'a few' residential connections (think fiber >500 Mbps upload) in each region, with some x86 server behind each to transcode / store?

The idea being to self-host the whole infra between users themselves, those willing to plug a desktop/server somewhere.

I figure you'd only need a basic load balancer in an actual cloud (always on) which redirects to whichever server is available enough.

Any thought about any of this?
