Hello!

Regarding the update: It will be finished next week. Thank you for your patience!

Regarding scaling Jot-server: By default, it can handle several thousand connections and work with multiple domains without any issues. We have never had problems with it overloading before.

About domains: You should use the IPs of the sites from which users are allowed to connect to the Jot-server. The GitHub version is not finished yet, but domains should work fine for the current version 1.0.3. I will prepare it next week, and it will work as expected for the latest version 1.0.4 as well.
