Is there a relay tech you are working on for this? I have resisted splitting my time, but I have the idea in my head clearly, using rust and LMDB and the indexes all worked out, it would be a binary plus a systemd init script, that creates a data dir and config file, no libraries or junk to install.
[I try to do the opposite of what Ruby did to me --- ruby fucked one of my servers once, trying to install mastodon or owncloud or something like that years ago, requiring boatloads of shit that broke other software that used different versions of that same shit. So I try to ship independent binaries with no dependencies]
