Hi, I am working on the Jupyter Realtime Collaboration project (https://github.com/jupyterlab/rtc) and one of the requirement is to avoid Node.js as dependency for the user (we set Python only as dependency).

I understand that the Automerge Server requires Node.js.

Are there any plan or ways to have a Python implementation of the Automerge server?

Is it completely automerge agnostic? I would expect the interest in a topic resided in the content of the automerge CRDT messages?

No, the "topic" in this sense generally represents one Automerge document or a set of Automerge documents (e.g. a DocSet, or what Hypermerge and Cevitxe both refer to as a repository).
