>How well does this scale? Are peers all necessarily running in major cloud environments?

The network scales very well. The network is divided into multiple GeoZones. We can add remove these zones easily. GeoZones are not connected to each other, so there is no single point of failure. Actually the major cloud envs are the most expensive possible variants for Peers. Bare metal servers are much cheaper in our case.

>Do you imagine seeing peers in the form of smaller players with beefy home setups?

Home internet has a couple of disadvantages: - traffic is not "unlimited". Xfinity doesn't allow you more than 1 Tb in and out traffic per month - home internet is asymmetrical: you could have 1 Gbps in and only 5 Mbps out.
