This will let you start a program from within the browser. It will not let you run arbitrary Python inside the browser but it doesn't sound like that's your goal. If you goal is "user can go to site, click button, hit OK on confirmation box, and launch arbitrary Python code", then the mime type solution is probably the best bet. Just make your own custom extension which will launch the python interpreter on your file. Give it a mime type, and serve regular .py files with that extension and mime type. IE will start the interpreter in a new process and pass your file along. To verify the file's signature, you could simply create a custom interpreter by making a console app that takes a file, checks a sig, then runs the file against an embedded interpreter. Embedding the interpreter is simple enough. > I can code this myself, but prefer to use some open source project, if it > exists. I don't know of any such. Heck, if you don't care about checking the signature on the file before running, your "project" could consist of a .reg file that sets up your extension/file type/mime type. Do an MSI if you want to get really fancy, but all you really need to do is add a couple entries to the registry. Of course, everything's a lot harder if you want to run within the browser. Having the browser ask the user for permission then launch a new process is easy. Building an integrated experience that hosts Python inside the browser sandbox is a lot harder - and probably not necessary. -- http://mail.python.org/mailman/listinfo/python-list
