The same rules apply in New Ports as everywhere else folks: If nobody has responded, use the edit button. It's there for a reason.

I actualized the project page and I did add that link :) - nice, we have a lot to learn from others projects. That project is really near from this one, It just not have external SRAM, display and not designed with Rockbox in mind. I contacted the author and invited him to look/join this project.
I also put on list the DAC TLV320AIC23B and added the good points of her to list. This IC is used in ARM_MP3/AAC_Player and in the DSPdap projects. Are we ok with this DAC IC?
I had look for ARM9 development boards and I saw they are much more expensive that this one ATNGW100, which I found for $73 at mouser electronics or about $80 at Digikey! I am with a feeling that we should go for ARM9, however, looks like this AVR32 do more DMIPS than ARM9 and with less energy, also is cheap the dev board.
I had the idea of contact companies as Olimex (in future working version) asking for support at assembly and selling the player. Olimex build and sell MOD-MP3 MP3 PLAYER MODULE WITH VS1002 MP3 DECODER/ENCODER, they could do the same for this project - http://www.olimex.com/dev/mod-mp3.html
Also I will ask to the company where I work a possible price for 50 units.
At IRC some questions were asked, as If this player needs Real Time Clock or not, 32MB of SDRAM or not, etc... - I would like to redefine the minimum hardware for first version of the player. Can someone help? Thank you.
