In this case, the private key is not protecting content
It does protect content, somewhat—iTunes decrypts (and decompresses and recompresses as Apple Lossless) DRMed audio before sending it to an Airport Express. Emulating an Airport Express allows one to obtain the decrypted audio, though not in its original oompressed form; it's no more of a hole than burning to a CD.
JavaScript/ECMAScript really is an interesting language; the way objects work takes some getting used to, but it's powerful, and definitely definitely not a toy language. It's when you bring the HTML DOM and browser inconsistencies into the equation that things start to get painful.

So it's an arms race, then?
