I don't think this would do it.  There is no guarentee that these types 
resolve to the same underlying type on the machine.  That is _uint32 
guarenties that it will hold a 32 bit number but doesn't guarentee that it 
is in fact a 32 bit number and may well be a 64 bit number on a particular 
platform.  These are just typedefs for native types guarenteed to be able to 
hold an integer of the required size. The native binary serialization will 
is built for speed and does no conversion.  The portable binary archive is 
what you want here, but as I mentioned before - its up to an interested 
party to finish.
