Wait, you're going to allow paying members to embed your paywall-protected videos on other sites to be viewed by non-members for free? If so, could I just register mixergyfreeinterviews.com and offer your entire archive there?

The free-embed idea is definitely risky, but it might help if you require there to be a certain amount of unique text/editorial surrounding the embedded video in order to avoid abuse. Otherwise, I'm going out right now to register that domain.
