Sony DADC & key2audio

I have recently purchased an audio CD that I believe to be protected by the new key2audio scheme adopted by Sony DADC, and I’ve not been able to find any information on the CD Freaks web site or this forum about how to circumvent this protection scheme. I believe Sony DADC uses the SecuROM scheme on the CD-ROMs it produces, so maybe key2audio is similar. Does anyone know anything about key2audio, particularly how to crack it?
