I submitted a pull request at https://github.com/pointbiz/bitaddress.org/pull/8 . (Edit: demo page at http://scintill.github.com/bitaddress.org-bip38.html )

I'm open to suggestions on improvements, or requests on other ways to package it up. The core code is pretty short and simple, but it depends on EC crypto, biginteger, AES, SHA256, scrypt, and Base58 coding, so could need some adjustment if anyone would like to use it outside of the bitaddress.org page. I may also release my scrypt code separately as it looks like there are no other browser-ready implementations.

Please send the bounty to 1GSo3Z3fgsvUH6yKr6s8kJHMFDWvLEuXjs, and thank you!

Congrats, I was nearly done but had some annoying bug left. I'll check performance in firefox and see if my code happens to do better though. (Unlikely though if your scrypt is also based on this one: https://github.com/cheongwy/node-scrypt-js)

Yes, my scrypt is based on that, replacing the node module dependencies with Crypto-JS functions. I also used Web Workers to do 2 scrypt threads in parallel.

Cool. How about also adding an option to bitaddress.org's paper wallet to allow generation of the encrypted private key and bitcoin address. I would even go so far as to not show the unencrypted version at all.

That's exactly what I want. I will give 10 BTC bounty for someone to create a pull request to modify bitaddress.org to give me an option to create an encrypted paper wallet using BIP 38.
See: https://bitcointalk.org/index.php?topic=139969.0

Done, just cleaning up the code for the pull request. I'll have it ready in a while. The only problem (other than the speed) is that the BIP38 encrypted keys are longer than the height of the pretty notes and the font is already pretty small. The original image for the note needs changing to accommodate. Also needs to change 'Private key' to 'Private key (BIP38 encrypted)' or something. My graphics/css manipulation skills are awful, so I can't really help.
