[Feature] Dedicated proxies

Most of ZeroNet users doesn't realizes it, but we need distributed servers, that acts as super peers, with reliable speed and bigger files seeded (for sample, distributed servers for video site or search engines, with lots of texts/data crawled and distributed).

Sample scenario:

KopyKate haves lots of users and videos, and users needs to search videos.
A single video index can be about 5 GB. Users needs to download this whole data? But they can temporary download/seed (https://github.com/HelloZeroNet/ZeroNet/issues/1603 and https://github.com/HelloZeroNet/ZeroNet/issues/1602) this data from distributed hubs, or simply tempseed/download it from any server (distributed file servers of choice, not centralized).

Another thing to consider:

Clearnet users wants to watch exclusive videos on KopyKate, without accessing a proxy.
They simply access kopykate.com, without the sensation that they are on ZeroNet.
Simply prompted to register on a ID provider (zeroid.com/kxoid.com?), do the signup, the seed is downloaded as text file (https://github.com/HelloZeroNet/ZeroNet/issues/902 - easier than copy/write, like some wallets are downloadable as text files) be redirected back to KopyKate.com (https://github.com/HelloZeroNet/ZeroNet/issues/1580) and login.

Also, data searcheable on clearnet search engines such as Google/Bing (https://github.com/HelloZeroNet/ZeroNet/issues/1596).

The issue does not name files, tests, or an entry point. Review the linked issues about temporary seeding, downloadable identity seeds, clearnet access, and search indexing first; the work is not defined enough to establish a concrete implementation or completion criteria.
