I think it makes a lot of sense. That's one of the reasons the Etoys activity bundle is but a tiny wrapper. Etoys works as stand-alone application in Gnome and as activity in Sugar.

Yes. Etoys switches the tool bar, e.g., the insert object/keep a copy buttons are replaced by file load/save buttons, the sharing button goes away, a full-screen button is added. The file format is the same, but different code paths are used.

Right on.
