Hi Adrian,

I am afraid that I will not have time to investigate Cocalc compatability
in the near future (not before the 2.1 release in any case), but I am
interested to include whatever it takes to get this working.

I think that Max also had some plans related to Jupyter, which also has
a TeXmacs-like generic mechanism to talk to plug-ins.  It would be nice
if someone had the time to write a good Jupyter plug-in for TeXmacs.

Best wishes, --Joris
