Well, the GMF runtime is of course a runtime thing, so you can't install
it in your IDE, only in the target platform.

Yes, that's an interesting use case.

No, you often will want a full EMF runtime on the server side, but
there's just no resource/funding to further develop such interesting things.

Yes, that would be interesting.

Yes, you'd need to write your own versions of some of the layers, i.e.,
communication and UI. There really isn't any significant active development
