This will either turn silly or be a very important case precedent for both sides involved.
http://www.zeropaid.com/news/9323/Record%20Labels%20Sue%20Irish%20ISP,%20Demand%20Music%20Piracy%20FilteringEMI, Sony BMG, Universal Music, and Warner Music take Eircom to court to force it to begin blocking illegal P2P downloads of copyrighted music.
In what's being called a first of its kind in the war on illegal file-sharing by copyright holders in Ireland, the so-called "Big 4" music labels have banded together to sue the Irish ISP Eircom in order to force it to begin blocking P2P music downloads by its subscribers.
They want Eircom to begin using filtering software that prevents its customers from using P2P and file-sharing services to illegally download copyrighted music despite the fact that existing law in that country makes no requirement that it monitor the traffic on its network for illegal behavior.
Previously, cases of illegal file-sharing merely targeted individual users and not network service providers themselves.
In most countries the law clearly states its illegal for the ISP to "inspect traffic", specifically national and european data protection laws, this activity could also be a breach of article 8 of the European human rights convention guaranteeing the right to privacy.
They really are playing with fire this time, lets hope they get their fingers burned.
