What feature would you like?
The AirPort Express requires encryption when streaming. This is well known and reverse engineered, so it shouldn't be that hard to implement. Just need to do it.

Describe the solution you'd like
No particular keys needs to be provided by the user, the private and public keys used for the crypto needs to be bundled. Otherwise this should be transparent (other than the check for supported cryptos needs to be changed).

Any other information to share?
