Japan to review guidelines on traffic shaping?

Japan instituted its Guidelines on Traffic Shaping in April 2008 (thanks to Marvin Sirbu for the link) - which is an agreement between ISPs following discussion with regulators and content industries.

It is a narrow exception to the net neutrality principle, based on throttling P2P - the fibre networks in Japan have been used by P2P 'seeders' (megahubs) to use up to 50% of the network's capacity by only 1% of subscribers.

It has a review clause, and in view of reviews in the US, Europe, Canada et al, it will be interesting to see what any review produces.
