It seems to be rather difficult to get a standard answer to 
the question:

"how to develop highly responsive interactive web applications"

A lot of effort is going to webify applications with Java Struts 
and similar techniques. You can create highly dynamic but still 
page based web apps. The more interactive the application is -  
a lot of ui updates necessary within user interaction - the more
network traffic and page rendering by the browser has to be done.

You can use Java applets but many people dont like it because
of its akward AWT based user interface.

Of course there are similar python techniques to the latter.

Some other web based client server projects I am aware of:

XWT is an interesting project (www.xwt.org). It is browser 
and OS independant. It only needs a Java or ActiveX enabled
browser on the client side and supports a self installing
thin client component (ActiveX component or Java jar file).
The ultimate solution for the software deployment problem?
Not python enabled so far, but they discussed the usage
of Jython rather than Rhino as scripting framework inside
the Java based client component.

Picogui (www.picogui.org) is another one with a rather fat
client software to display (potentially python based) 
applications over the web.

And there is curl and .....

I am interested in a discussion of usuable and reliable 
frameworks for this problem (beside Struts and Java applets)
