I think you have converged on some sort of JS generator.
"future-proof' is an impossibility, but that's a moot point.

OK, this is going to be the tough one. I've noodled this before with
another company xtuple who uses QT for their UI and postgresql for
their backend. The tough part is that you can't easily have two
different technologies messing with the backend data simultaneously.
If you intend to keep your python thick client interface and have a
web interface work at the same time. Are you ? I guess that is an
important question.

Many of these server side frameworks have their own logic for data
consistency which you would have to adopt in the python client. ie
optimistic vs pessimistic locking of records.

If you are indeed serious about keeping both clients web, and thick
then I would think that both of them would have to access the data
through some middleware in order to maintain data integrity and keep
one codebase.

Yes, raw javascript is only for masochists.

These are very good points which I dont think there is a good answer
for. At the moment the only thing I can think of is using them like a
keyboard wedge.
