Can you add these in a separate CL so we don't need to get jam to re-review this
one?

He told me not to put implementation in content/public, which these are, so he
may want us to add an Event enumerator to ask the BluetoothDispatcherHost to
show the links.

Shifted this over to BluetoothDispatcherHost. :)
