It's an implementation of protocol::SessionManager, not SessionClient?

[Sergey Ulanov, 2011/09/12 19:50:50]

Done.

+class PepperSessionManager : public protocol::SessionManager,
+                             public SignalStrategy::Listener {
+ public:
+  explicit PepperSessionManager(pp::Instance* pp_instance);
+  virtual ~PepperSessionManager();
+
+  // SessionManager interface.

nit: I prefer to qualify interface names in comments.

[Sergey Ulanov, 2011/09/12 19:50:50]

This class is defined in remoting::protocol namespace, so I don't think that we
need to qualify interface here (but it would make sense if SessionManager was
defined in a different namespace).
