[QGIS-Developer] Interaction API?

I have to apologize and give a little context. I teach geographic scripting
at a local university. Students come from the previous geomatics course
with Arc.
Since I have no intention to teach Arc scripting, I have been doing it for
several years now happily using a scripting environment based on Geoscript
Groovy [1].
So we are talking about a completely different programming language.
In the last year I have been able to pull some of them over to QGIS, but
the traction is low. So I was hoping to be able to attach to some APi to
load results into a running QGIS instance. That would be really cool,
surely convince them and I would have been able to develop the geoscript
part necessary to my environment.

In the meanwhile I read Gio's comment: "Another option could be run a
"micro server" inside a pyqgis plugin and serve an ad-hoc API from it :)"

Yes, that would have been my dream :-)

Thanks for your comments.

Andrea
