I know that the idea of any modchip must be a long time to go. It took bunny a long time, and he came across many barriers, mainly 'DMCA' Digital Millennium Copyright Act., and the ability to freely discuss his findings with other hackers. Even if it could be cracked, it takes time to test then mass produce any modchip.
However, I have just checked out bunnies site, and he has a link that shows that you can buy a report from an American company that has stripped and analyzed the 360.http://www.chipworks.com/news/2005_xbox360.asp
I guess this will just be basic info, as they would surely be bound by DMCA, but it's a start.
All little buts of info, combined, and we should see slow progress, but the idea of any modchip being available with a month - WHAT, I'll will eat my hat if this happens.
