In general it's bad form to require a source of a mel script to trigger
execution. If you make a global mel proc in the script with the same name
as the script, you can just do:
mel.eval("test");
And that will execute it.

It's non trivial (since Maya has nothing built in to do this), but you find
the 3 verts closest to your point, and their weights. If the point isn't
exactly on that tri the 3 verts define, you need to use the vector maths to
project it down to that plane. You can then use some (roll your own)

Indeed there is: Python comes with the cPickle module, that lets you

that writing to your filesystem, but it also had a dumps (dump string) that

If you're trying to export stuff per frame over a long sequence, then you
want the calling code to control the frame step, not Maya's playback

the playback is *over*, not during playback. That being said, scriptJobs

It's possible you could get away

To my knowledge, Maya intercepts incoming commands as mel,
irregardless of send methodology. You can send any type of data you
want to Maya over the socket... but Maya will expect it to be mel when
it receives it. I've not used MayaPad, but maybe it does something
