If you can run it as a client application (i.e. not through the browser but still across the internet) - then this all seems quite easy to achieve. It also allows you to access the local filesystem without dropping out of Python or using ActiveX objects. If you know the version of Python the machines are using (or create a loader program using py2exe) then you only need dsitribute the 'pyc' bytecode files. (Making it *much* harder to hack for the average user). I don't know if anyone has released an 'auto-update' framework for applications, but it would be a nice project. I guess each time it's needed the requirements will be slightly different though - but there are a lot of general principles.

I have used Java Web Start to distribute Jython applications from a web page. There are a few glitches getting it set up but then it works well.

I need READ access to the users local disk storage. Can I do this in Javascript, or should I bite the bullet and turn to ActiveX? This can only be done with scripts by disabling or bypassing browser security restrictions. It can't even be done by zone in IE, only globally, and I don't know if you can do it at all in Mozilla based browsers. A signed activex control or Java Applet (that registers for the appropriate sandbox permissions) will work. Overall, it's probably simplest not to do any of these and simply write a standard application that you have users download and run. This is the safest and most straightforward solution, and honestly what you save in configuration managment when people call you wondering why it doesn't work is probably worth the extra effort it takes them to actually run your application. -- http://mail.python.org/mailman/listinfo/python-list -- http://mail.python.org/mailman/listinfo/python-list
