Simon McCalla, Nominet’s CTO, had some answers: primarily, they’re constantly trying to improve the accuracy and reliability of the Whois database, but it’s only a very small criminal element that engage in false domain name registration. The discussion that kicked off this week’s Parliament and Internet conference revolved around cybersecurity and trust online, harmlessly at first. Then Helen Goodman (Labour – Bishop Auckland), the shadow minister for Culture, Media, and Sport, raised a question: what was Nominet doing to get rid of anonymity online.

If you want to help musicians, the first and most important thing you should do is improve the industry’s standard contracts and employment practices. Any or all of those things would make far more difference to the average musician’s lifetime income than an extra 45 years of copyright. No one is saying – not even Courtney Love – that musicians deserve charity. We could put limits on what kind of clauses a recording company is allowed to impose on first-time recording artists. And we could require the return of rights to the performers in the event of a recording’s going out of print. We protect workers in other industries from exploitation; why should we make an exception for musicians. But we could reform UK bankruptcy law so that companies acquiring defunct labels are required to shoulder ongoing royalty payment obligations as well as the exploitable assets of the back catalogue. We could set minimums for what is owed to session musicians.
