OK, we really need to stop being abstract and say what operations we want.

I think the minimal functionality I'd want is:

    convert record to JSON
    convert JSON to record
    extract a value, or set of values, from JSON
    composition of JSON

Now all the libraries I have looked at (briefly) would require some code 
to provide for those, possibly quite a bit of code, but that doesn't 
mean we should just start from scratch and write our own JSON parser too.

cheers
