Yeah! :)

I did the same at work.

Without reading your code carefully, I can think of two optimizations 
that may prove to be useful:

- If a struct contains all bitwise copyable members, instead of 
(de)serializing each member individually, the whole struct can by 
memcpy'ed. This may be a performance gain especially for arrays of 
structs: You can memcpy the whole array at once.

- Instead of allocating memory for each value (e.g. for arrays with 
'new'), you can maintain a function-static buffer and reuse it, 
allocating only as the current buffer is not large enough for new data. 
(No worries with multi-threading because each thread will have its own 
function-static buffer.)
