How about calling Unregister() in the destructor?

[keybuk, 2013/04/17 22:38:35]

The intent is that Unregister() *calls* the destructor - will clarify in the
comments

+}
+
+
+// static
+void BluetoothProfile::Register(const std::string& uuid,
+                                const ProfileCallback& callback) {
+  // TODO(keybuk): Implement selection of the appropriate BluetoothProfile
+  // subclass just like BluetoothAdapterFactory

Are we going to follow the similar structure as BluetoothAdapterFactory? If so
then we will have a lazy instance of a list of profiles in this file? shouldn't
we also make Unregister static? I can't clearly see how we could delete the
profile if Unregister() is a member function of BluetoothProfile.

As discussed, No; it should be entirely okay to deal with that in other ways

+  callback.Run(NULL);
+}
+
+
+}  // namespace device
