Display entities are accessed by driver using notifiers. Any driver can register a display entity notifier with the CDF, which then calls the notifier when a matching display entity is registered.
The framebuffer layer has some similar 'anyone can' type notifier behaviour and its not a good thing. That kind of "any one can" behaviour leads to some really horrible messes unless the connections and the locking are well defined IMHO. Alan
