It is not so much that rjson is implemented in R that makes it slow,
just that it does not use vectorized operations.
The package RJSONIO
http://www.omegahat.org/RJSONIO
can be used as a drop-in replacement for rjson and was written to be
faster (by using vectorized operations) and extensible via S4 methods.
(We use R to JSON in the SVGAnnotation, FlashMXML and RGraphicsDevice
packages.)

Is there a *fast* converter between JSON and R? I'm aware of the rjson
package, but it is implemented in R, and it is too slow for my purposes.
TIA!
