Ok sigsegv, maybe I'm thinking of this wrong then.
How about this instead: is there a way to provide, say, a Python/Tkinter script in such a way that, when a user comes to my website and clicks on a given link, the python/tk script is downloaded to their ~/temp directory (well, after asking permission of course) and then run from there?
The idea being, I don't want to make my user have to download a program, find out where they downloaded it to, and then run it from a command line. That is, if I could get my non-tech brother to use a GNU/Linux box, I'd like for him to be able to go to my website, click on a link, and get to automatically try out my latest Python/Tkinter script. Is there a way to do *that*?
