BTW: Is there any plan for guest code already?  Should it stay within 
the qemu source tree, in a guest/ directory maybe?  pvmouse daemon would 
live there, also the upcoming guest agent bits.

Before finally committing to some protocol I'd like to have at least a 
simple proof-of-concept which is able to handle all the mouse events the 
current qemu mouse infrastructure is able to handle.

Oh, and we'll have to define endianness of course so it keeps working if 
host and guest have a different byteorder.  I'd suggest to pick network 
byte order aka bigendian.

cheers,
