I=E2=80=99m thinking of grabbing some code from = https://github.com/zk-phi/togetherly/ It uses different color to distinguish users. I can probably then add = some way to toggle displaying full user name with some hotkey to toggle. Also need to add a list of connected users and color. I know that emacs=E2=80=99s make-network-process handles TLS if acting = as client, but seems that the server doesn=E2=80=99t. Any idea?=20 Or we could rely on some TLS proxy. > - make sure that it can be started remotely on public Internet server > through SSH client, where each of users would then connected.

Does it have one single temporary password of a server or instead a user-password model? If it=E2=80=99s the former then is it = reasonable to just send plain password (over TLS connection)? Then that will be quick to implement. > On Oct 5, 2020, at 12:02 AM, Jean Louis wrote: >=20 > * Qiantan Hong [2020-10-05 03:00]: >> I=E2=80=99ve finished the initial work for a CRDT based >> collaborative editing Elisp package.
