Any projects to provide Javascript-style client-side browser access via Python?

[Kenneth McDonald]

I'm curious about this because, quite aside their function as web  
browsers, it is now possible to build some very useable interfaces  
using browsers with HTML, CSS, and JavaScript. (The biggest problem  
is still the lack of a decent text widget.) However, JavaScript isn't  
really a good language for building complex applications, and it  
would be very cool if there were some way to use Python to replace  
client-side JavaScript, in order to gain access the DOM.

So anyone know if there are projects underway on this?

Thanks,
Ken
