Well isn't that a shitter. But seriously, you can't tell me that all the companies and individuals that have a hand in XBOX modchips, hacking, softmods, etc. have NO IDEA about how to hack a firmware. The Dangerous Brothers aren't some rare anomoly. I'm highly surprised that it's taken THIS long for firmware hacks to even come to light as a working possibility.
From what i've seen all along the strongest and best people in the xbox scene have not been concerned with running backups so much as running homebrew. The original xbox (and now the 360, and all consoles during at least their first year or two) are sold for less than the cost of the components. That isn't true of any other electronics hardware. So being able to run apps "ad hoc" or run homebrew gives you a really high powered computer for a really low cost.
Since the only use for a DVD firmware mod is running backups it also is a LOT harder (if not completely impossible) to defend it in a court case related to the DMCA, since its only use is circumventing protection on copyrighted material. Thats where xbox modchips by themselves have managed to survive - there is the fair use piece for the hardware, allowing you to run applications/operating systems that aren't "sanctioned" by MS. Thats also why most xbox modchips either ship blank or with a Cromwell based bios on them, as neither of those choices allows you to run backups by itself.
Also, since MS controls the hardware 100%, it is possible for them to require that developers include code (to gain Xbox certification) that were to check for specific checksums or MD5 hashes of the DVD drive firmware or update the xbox dash to do so, that would negate the firmware hack anyway.
The really interesting part of that is that since the 360 has the 16 byte machine unique key in the dvd firmware, its shouldn't be possible for MS to use a similar mechanism (the MD5 hash or CRC) to ban machines via live, as each machine would have its own unique CRC/hash result.
But again, since the Digital Millenium Copyright Act would definitely allow MS to close up and seriously drop a hammer on anyone releasing a DVD firmware mod like this into the wild I don't think anyone who has the ability + skill to do it will risk releasing it.
