There's a much better/easier/faster way.  Chris Bell is working on
that.

Yes, that would be cool!  We should think about doing that.  We'd
have to make sure we dropped priviledges to a normal user before
invoking scripts, and perhaps would need to check for those scripts
being located in the user's area somewhere for security reasons.
Doable though.

Any of the developers want to take this on?

There's a new tag for the .geo file.  Check the README.MAPS or the
on-line help system for the details.  I think it's called REFRESH.
