I think Redhat does not honour the 'open source' attitude. Well, technically they do but it is obvious by their copyright policy
"You may only sell Redhat uncommercially and must not charge more than the cost of the media and p+p"
that they are not too keen on you getting their product without them getting your money (and lots of it too, Redhat costs almost as much as Windoze now!?)
What do you think?
