OK. I'll look at this and see what I can do, or what I can help  
others do. I talked to John Caron and Ethan Davis about it and we  
came to the conclusion that what I'll need to do is take the netCDF  
3.6 source distribution and drop it into my C++ client library. It's  
not completely trivial because I'll have to rename some things in  
your code (complete explanation elided) but it's not as if we need to  
add support for a 64 bit datatype to the DAP!

Is there anyone out there that would like to help with this?
