I bet you are, actually. You probably just don't know what to call it. ;-) There are advantages to learning the terminology -- but, just as with grammar, you don't have to be aware of it to use it.

I should add to that, the ability to do something equivalent to Java web-based applets - that is without giving up my access to C based Python libraries, like Numeric and VPython.

Not a feature request - just verbalizing.

I am, however, working on something that would allow you to run a GUI Python program like a Java program (on Jython) OR as a python application without changing the code. I am aiming to have this ready before the end of the year at the latest, as I plan to begin developing for it next year as the client side of my current project ( http://www.anansispaceworks.net/NaryaInfo/ ). You can, of course, currently write two versions of a program to run in these two environments now (Jython provides this, http://www.jython.org ), but there is no shared GUI environment or even canvas object. The mapping between the different available packages isn't that complicated, but no one has actually made the leap of spanning them. If you are content to force your users to download Sun's Java plugin so they can run Java2+Swing applets, then you *can* code to AnyGUI and use the Java-Swing backend for the web, and any of several GUIs for running natively. But that won't run in "stock" proprietary browsers or free browsers (generally speaking, though, free browsers require a Java OJI plugin to run any kind of Java). My research says the easiest solution is to write a Jython+Java1+AWT renderer for PyUI ( http://pyui.sourceforge.net ), and to improve the existing PyGame+SDL renderer (which should support at least Linux, Unix, Windows, Mac, BeOS, and should be portable to just about anything), so that they are truly 100% compatible. This looks like 200 - 500 lines of Python code added to PyUI. Then application/applets can be written on PyUI directly -- OR, one could finish the PyUI backend for AnyGUI ( http://anygui.sourceforge.net ), and code on the AnyGUI API (which gives the end-user the additional possibility of running the application with wxWindows, Tkinter, PyGTK, and other Python GUIs if they prefer). Unfortunately, this is unlikely to work for something like VPython (unless you are prepared to do a *lot* of work to port it), which uses extension modules. Would love to see that work, of course -- but it's a little beyond me. ;-D I understand that Numeric has in fact been ported to Jython (as a Java extension), which is understandable considering that Jython and Numeric were written by the same person. I don't have details on that, though. Someday, it might be possible to have a Python plugin that runs Python applets, just as the Sun Java plugin runs Java2 applets. But my initial research into that suggests it will take a lot more work. Part of the attraction of the approach I'm taking, though, is that it makes such a solution viable, and creates a motivation to create the applets that such a system would run. If and when there is a supply of applets that could be sped up and/or extended by a native Python applet plugin, there will be a demand to create one. This is one path to a Free applet platform, and it would be able to run native extension modules, as you want. The other is making the KaffeOJI or other Free JVM fully compatible. But that of course, won't run native extension modules, nor would it be as fast. That's perhaps reason enough to prefer the native Python applet plugin approach. I'm getting a little off-topic here, but I do think this will be good for education, by making the software more accessible.
