Yes this is the right way of doing this (I have been experimenting a bit yesterday). However have a blocking call would be really nice for casual programmers, like so many physicists, who have no idea what eventloops and threads are. I think that for such a blocking call to work, all we would need is a way to start and stop the eventloop (I am talking in wx terms, the only GUI toolkit I know). That way when a script call ginput the ginput call adds a few callbacks to the canvas (that's the easy part) and starts the eventloop. The callbacks stop the eventloop when the right number of points as been acquired. Now I have no clue if this is possible, but that would certainly make writing small interactive scripts much easier.
