Oh yes, good catch, I forgot they were now opensourced :)
Yes, protocol buffers are pretty cool and if you want to transmit in
binary, they are a likely a better option than binary plist (I was
talking about ascii plist).

never tried either, but it would be good to see if they do and fix it
if they don't...

Now would be fun is DO through protocol buffers ;-) [reusing etoile's
serialisation code?]
