Sorry, I wasn't clear enough. I'm thinking of using a standard
serializer. So what's being sent is standard JSON.

Yes, and I did look search before asking (apologies for not saying
that). Didn't find anything.

Also a good point. The application I have in mind is a database that
contains help information, and I want deliver it in large pieces (or
even as one large piece) to a help widget that appears on a web page.
If you're interested, here's an example of what I want to deliver

except that I want the help data to come from something like
http://www.mathtran.org/formulas/
