You've got partway there, but a one-way mirror gives total reflection on one side and partial reflection on the other, which is Normal dependent. For a two-way mirror, it's just partially reflective in both directions, so you just want a constant factor input. If you want it to be something other than 50% reflective in both directions, though, then you'll probably need to blend based on the normal as well.
Verbosity: Profusely promulgating Graham's number epics of complete and utter verbiage by the metric monkey barrel.
