I've wanted to make my own version for a while, but using a RBP (which I use for my media consumption anyway) was previously a deterrent.

I think you should make a HDCP pass-thru box because the easy of installation and practicality makes it more desirable to consumers (myself included). I have previously written software that breaks HDCP encryption as well as does a slew of other work arounds that other companies -- despite saying they do not -- actually employ to make input switching faster.

If you need to talk to anyone about HDCP let me know; I can either help or get you in touch with some people who can.
