Just looking at the screen shots on your webpage, its looking quite good. Make sure if people are trying to use their F drive that they are aware they have to format it.
Oh, and I would love to see the inclusion of a version of dvd2xbox and/or boxXplorer in it as well so that people without lan could install the exploit, and then be able to continue to install new stuff too.
I remeber seeing something on xboxmediaplayer.de about an autoinstall app for homebrew, once you've got this working, maybe that could be an easy extension, so people could just through in a cd and evox would auto-install it?
(I dont have a lan, i just use boxXplorer and xISO)
