There are at least 6 standalone, pure C [1] json parsers available
already, some of which let you do json formatting too. So writing a
new parser, or untangling one from python seems like more trouble than
its worth to me. Likewise for generating formatted JSON output.
For QMP experimentation in libvirt I've started off by just grabbing
the json.h & json.c files from an existing impl
http://mjson.svn.sourceforge.net/viewvc/mjson/trunk/src/
which are LGPLv2+ licensed, and copied them into libvirt source tree.
They provide quite a nice simple API for both parsing & formatting
and integrate very easily with our codebase.

Daniel
