Cournal allows multiple users to annotate PDF files in real-time.
Why not extend Xournal?
There have been numerous discussions over many years on the Xournal mailing list and Xournal++ even had experimental networking support, but it didn't work out. So I started Cournal, which got networking support just after PDF viewing and simple drawing was done. Therefore it was designed with networking in mind from scratch.
Does it work yet?
Yes, but you might miss some features (see next section ;-)).

Start Cournal, select "Annotate PDF" and then "Connect to Server".
The file format is compatible to Xournals .xoj files, but Cournal is not able to open all .xoj files created by Xournal, because it doesn't support all features of the file format. The other way around should work though.
