If you use Jython and AWT as windowing toolkit (maybe swing is also 
possible in current browsers), than you can ship a carefully designed 
python application as .jar, even as an applet, if you want to. There's 
seemless interaction between Python, Java and most other JVM compilable 
languages (http://grunge.cs.tu-berlin.de/~tolk/vmlanguages.html seems 
to have a rather complete list on those).
