Hey Boris, curious question here. If you could do an NFS mount to one of these collaborative IDEs so that you could compile on another VM but still get the collaboration of the IDE, would that be a nice compromise?
I think that this solution would work as long as I didn't have to re-init everything each session. Some of the IDEs, not exclusive to free options, dump the sessions fairly aggressively. (And it ends up being a new 'box' with only the project files remaining consistent) Which makes sense, but not helpful in my particular use case.
