@jarbus @hund You can host a mumble server on a cheap computer though instead of the supercomputer that matrix requires.

@jarbus @hund Ya, I selfhost xmpp+mumble. It's not perfect but it gets the job done. The current state of matrix is not good:

It's not enough that the server software is free software and federated. The server software must be easy, cheap, and simple to self host.
