Nail,

I'd love to see the result you'd get by using one of number of JSON 
parsers implemented by Boost.Spirit.  A number of them pop up by 
googling "C++ JSON spirit" including one by our own Michael Caisse.  I'd 
also be curious to know the compile time as well as the runtime for the 
programs above.
