Well, remember, JS == QML, basically. So I don't see why not...

A dbus interface sounds the most reasonable, here -- in that case.

In general I'd say yes, although it depends on what you are referring
to when you say "active". DataEngines do not exist until they are
called upon. When they are no longer being used (e.g. applet dies)
they will die as well.

That would be fine. Other dataengines create dbus interfaces as well,
so you are not alone in your need.
