I read an article in CNET mentioning that the RIAA is talking to ISPs to shut down Napster like services specifically OpenNap in the US and abroad. They suggest that Gnutella is next in their list. I'm fairly technical but I do not know if Gnutella can be shut down/blocked trough an ISP. This highly concerns me since I use Gnutella a lot.

Is this true? What are your thoughts?.
