What I meant is it would be nice to have a common protocol that allow 2 persons with different editors preference to do this kind of pair programming session without one having to ditch is preferred one.

For example, I can make do with intellij whose vim plugin is actually well made but the vimlike plugins for vscode are all useless.

Before starting Hopp and searching for alternatives, one of the things I really liked was Zed's paradigm around collaboration, with its Collab panel and Channels.

The streaming quality was also quite good with Zed. VSCode and JetBrains pairing features were a pain, as you needed to share a URL. The experience in general was not optimal. Not something you want to do multiple times a day.

With Zed, the only drawback was that the scope is always IDE (view mode also for whole screen). But from my experience, pairing is more than your IDE. It's terminal, debugging your unnecessarily complex AWS setup, fiddling with Grafana dashboards, etc.
