We're just starting to analyze Che for our coding school. Wouldn't all this just be possible with the Terminal? I'm not saying plugins aren't good, just trying to see if the terminal is a full featured one that would support something like, for example, installing the heroku toolbelt.
I haven't even started with a real test, just reading about it, so sorry for my lack of research, I'm just reading through the features (https://www.eclipse.org/che/features/) and saw the terminal, which is fundamental for us.
