I guess you are just not exposing those?
My concern is that a client could remove properties installed by the 
server or a driver.

In the readonly case, I think it should be possible to tell a property 
which refuses to be set due to the value apart from a property which 
generally is 'read-only', i.e. has a always-fail setter or some 
unexposed flag. Could be BadValue vs. BadMatch, but I'm missing it in 
the ChangeDeviceProperty spec (readonly is arguably a type mismatch).

Otherwise, I'm fine.

Cheers,
