You could put the ID in the base Packet type. That should minimize the chances of mismatch.
Right now I'm already putting the ID as a static constant variable in each derived type. I don't see a way to set the ID in the base Packet class, since that would more than likely require CRTP or something. From what I have seen the Packet base class cannot be a template. I suppose you could do this if you used 3 levels of inheritance, but that seems ugly.
I'm thinking of a non static member variable in the base class, which can be set in the constructor.

Is there any reason why the ID needs to be available at runtime? Instead of your specialization, I do: class WalkPacket : Packet { static const PacketId ID = PID_WALKPACKET; }; Is there any reason why this isn't sufficient?
