Looks good.  Personally I'm not a huge fan of having a distribution
download stuff from the internet - servers break, URLs change etc, and
tend more to just snapshot a particular release into the distribution
itself.

But, generally as a guide for this sort of stuff I'm sure it will be
useful to people.

Cheers,

John
