Sorry if it came across as if I was saying I thought it would be easy,
because I don't. But I also don't think it would be impossible,
especially with the amount of money at stake here. What is more
rankling is that these associations believe, in the face of huge
evidence to the contrary, that unpopular laws passed by heavy handed
lobbying is going to prevent people from trading copyrighted material
on-line when they believe that it is massively overpriced and/or unfair.
The solution may not be technical, it may be as easy as treating
customers as desirable, rather than as criminal, and offering products
at reasonable prices in a value-added way (i.e. perhaps easier to find,
or at higher quality). I think the Music industry is finally getting
closer to the right direction, the on-line services are far better than
anything previously available. If they can clear up some of the
fair-use restrictions I'd say it would be good enough. I'd love to see
the artists come up with a large scale grass-roots direct to consumer
alternative though. Wouldn't you love to be able to buy a CD knowing
that all the proceeds minus the website operating costs went to the artist?
