I thought I would share some of the things I've learned about bootmii so far:
I tried to install this on 3.2E using Homebrew channel 1.01 and it locked up with a blank screen when running the installer elf and wouldn't install.
I renamed the installer as boot.dol in the root directory of my SD card and then used bannerbomb exploit and then it installed perfectly that time! I hope that helps anyone out there with the same issue.
BootMii is most useful if you have an older wii (eg 12 months+ old) and then you can install it using the "boot2" option, which inserts it before the system menu. This means that you can restore a nand backup if you brick your wii, which is something that hasn't previously been possible except using hardware to rewrite the nand chip. This allows for much greater experimentation with the wii.
If you have a newer wii, then its still useful to be able to backup/restore your nand, but you'll only be able to do this if your wii isn't completely bricked. For example if you upgraded in future and then wanted to downgrade again by loading in your nand backup that you made at an earlier point in time.
As far as I know, this installer, in combination with bannerbomb exploit, allows you to install the Homebrew channel, even on a virgin 4.0 wii, but its unlikely to be able to offer the full brick protection, but its still a lot better than attempting a dangerous downgrade of your 4.0 wii. I don't have a 4.0 virgin wii, but as far as I know its supposed to work for this.
Some earlier posters on this thread said you needed an internet connection to use this installer, that isn't correct, its fully offline installation.
When installed with the boot2 option (earlier wii's only), there is a scary delay of a few seconds when you power on your wii as it reads your SD card before bringing up the bootmii menu. Some people reported this takes longer, but it appears to be due to the type of SD card so you can try getting another one and see if its faster if you have this slowness problem. You can avoid this delay almost completely by removing the SD card during power-on or probably by deleting the bootmii folder it creates.
Personally, I'm quite happy to suffer this 5-10 second delay on my wii in exchange for full brick protection. Also the delay doesn't happen every time, it seems only to be during power on rather than during reset, so I'm not too bothered. If its possible for the bootmii team to improve these delays in future versions, then I'm sure its something they will do, but remember this is only their first beta and they are likely to have been cautious with their code rather than trying for blazing speed which might not work on everyone's different SD cards.
I'm very happy to see bootmii finally released and tip my hat to the skillz of everyone involved in bringing it to us. Its not useful for everyone, but for those it is useful for, its incredibly useful and something we've been waiting to see for a long time
