BTW, once HackMii Installer is working on 4.3, there's apparently a reasonably simple way you can install fake signed content (e.g. patched IOS) on any Wii, regardless of the installed IOS. The Wii just needs DVDx, which when HackMii Installer gets updated to work (as I'm sure it will soon), all Wiis can have.
You run DVDx, which gives you access to ahbprot, allowing you to disable MEM2 protection and patch the sig checking function of ES, which then lets you install fakesigned content e.g. a patched IOS. sven_p mentioned this on #wiidev last night, WiiPower, perhaps you could implement this in a new version of TBR (I'm sure you'll be able to work out how to do all that stuff, I haven't a clue, but apparently its not too hard, and you seem pretty good with that sort of thing
)
