Radiohead album advocacy

Good afternoon, I would like to place a pre-order for the radiohead download album but since I am an open-source user and a strong supporter of open formats, I would like to know if it you could possibly inform me of the digital format used in the download, I understand that while mp3 has a wider market acceptance, it is covered by patents and of inferior quality than the ogg/vorbis format, and of vastly inferior quality than the full lossless encoding of the flac format.

Also although software patents are still invalid in Europe, in the united states and other such countries the patents concerning the mp3 format make it technically illegal for Linux/open source users to use the mp3 codecs in order to listen to an mp3 download.

A Flac file however can be legally distributed and used without restrictions and there are free tools which allow anyone to transcode into their preferred lossy format to be used in their portable player, also flac is already supported by almost all players and is a de facto industry standard.

Also although apple has kept their users choice of codec artificially limited, there exists an alternative software for the ipod series and a number of several other digital audio players which adds support for nearly all codecs in existence and which is available free of charge as an open source project. You can find more information about this at www.rockbox.org

Also I would like to know if it would be possible to make the phone mobile number and the street address fields not mandatory for the download only option.

Thank you for your time, kind regards,
