Hmm well, a package to make the changes would save a reinstall if someone wanted to try it out
but then you'd probably end up with another autoten or the other one (I cant think of right now)
but anyway, I i guess they're all options which is what linux is all about, I'm sure someone would try it whichever route you went down.
Oh and there's another spin I forget to mention, Omega (Pug)
that ones got all the codecs and media stuff in it already
