I think the technique you talked about is an easier way to achieve a 
similar goal as the continuation-based frameworks.  While using 
continuations for web applications is an interesting idea, I don't think 
it's been shown to be successful.  It's certainly not something I'd want 
to implement on Python (even given the actual features to make it 
possible), and from what I've read of the Ruby projects that use it 
(Borges and Wee?), they aren't ready to implement production 
applications either.  The technique you present could be implemented on 
any framework, right now, with the expectation that it would work in a 
production situation.
