Yes, I had intended to do that but left it out.

Should it be a bitmask or just a button count?  Buttons really have no standard 
meaning so usually a button count is sufficient.
Some random thoughts:

   * multitouch capabilities would be good to design in a mouse protocol for 
2011, so having say 16 x/y pairs would be better
   * on mac os at least scrolling is not done by pressing virtual buttons, but 
by having a separate scroll interface that knows about velocity and such - 
maybe worth adding that to the protocol from the beginning too.

Features negotiation takes care of this.
