Just one comment - Django lets you render to JSON just as easily as
rendering to HTML (or XML). You just write your template as JSON and
set the MIME type for the response accordingly. Because I control my
JSON parsing on the client side, I set the MIME type to text/plain but
you could set to another if you wanted.
I realise that this doesn't actually solve your problem of combining
HTML and JSON in a response and I think one of the other comments
addresses this but I wanted to make the point that JSON by itself is
easy.
Cheers
