Neat.  Haven't encountered that page before.  To test it, I just did the following:

1.  I made a BIP38 address in bitaddress.org with the passphrase "tucker" (no quotes).  I got this: 6PfRsAUt4GoxgvLpfMAuPZnxK452gvdmbY2KcfBHFFJCQJKgGPZ9pSpdZH, with (apparently uncompressed) bitcoin address 1DoH8sE1twMQybnoFWpw7PZnJjNCuiDrfF

2.  I took that encrypted address to the details tab of that same webpage and entered "tucker" to get the decrypted private key of: L2xcepU1mUtYkbZeihcw1znmajibjgf6koG8szWQM4cpWGAjoqVb and a compressed addressed of 1CMwWVSH1fkifpbrkknYW1NCpk3pkD99fs (the uncompressed address given here matched what was shown in step 1 as expected)

3.  I took the decrypted private key over to bit2factor.org and asked it to encrypt it with the passphrase "tucker".  I got the same compressed bitcoin address of 1CMwWVSH1fkifpbrkknYW1NCpk3pkD99fs but the bip38 private key is shown as 6PYWAF9qqjk6ytZFbepaSDDk9oGb5gBwwgUP8cnaCgUa7LR4T6SJX9pLCQ.

Does anyone know why I didn't get the same bip38 key from bit2factor that I got from bitaddress.org?
