One thing I'd add as a suggestion: if they do a rolling release, hot-rebuild the package so that if you download an "Ubuntu rolling" ISO, you get a 100% up to the minute copy with all the latest security patches and so forth. This so that starting a new Ubuntu install is not annoying (which it would be if you basically had to throw away and redownload the whole OS as updates as soon as you installed).

There's already a daily ISO of the development release, so I imagine that would carry on under a rolling release.
