I'd like to add the the Piper Processing Layer (PL, aka Overflow) has
already been ported to Win32. The port is not complete yet, but it's
enough for many applications.

There is already a mecanism for binary (endian-independent)
serialization of objects to file or through network. It's fast enough to

with less than 5% CPU. For those interested, we'll soon release a demo.
