Big Music have won a legal case against Grokster in the US Supreme Court, allowing companies that operate file sharing services to be sued.
I'd suggest that this creates an opportunity for New Zealand. Some countries operate a system where a tax on blank media funds a "right to copy". We could do a similar thing with a small levy on bandwidth allowing a right to share files. The proceeds could be distributed to New Zealand musicians and other artists.
Having adopted such a scheme, we could pass laws sheltering NZ based companies from US and other litigation - this would be an economic boost as file sharing and other companies relocated here - we'd become a "data haven".
