I think this is a good idea. First one detail: for Pointertypechange, it 
would be better to use the value 32768 as 0 instead of 32767 or to use a 
16 bit two complement value.

Another point is that you should consider adding audio support. I can 
help you on that (maybe malc would be interested too !). A simple format 
could be 4 bit ADPCM at fixed frequency. Optionally A more advanced 
codec such as Vorbis could be used.
