Are you suggesting that we allow utilization of WSA with the additional third-party in-out MEP ONLY (if we were to provide it in the note) or assume that its also possible to use it with the in-out MEP? I am just trying to find out everyone's expectations here, since I missed the last concall. >Amy! >-- Thanks. --umit
