Now with everyone and their neighbor doing VoIP- I don't see how they can block it on every site. AOL, MSN, Yahoo, & google all have online calling programs.
It's pretty easy, the packets are well understood (ie it's easy to write rules that match the voip packets.) You don't block the sites, you block packets which "look" like VOIP calls.
Infact there is a company which sells software which allows an ISP to either block, or selectivly degrade VOIP service. (I think it's netqos.com) This is what the Net Neutrality issue is. Should an ISP be allowed to block Voip service, or even websites who haven't paid their "bandwidth" fee? You say imposible, I know, but think of how many people use Comcast as their ISP in the US?
Of course if your cleaver you can get around this, by using a VPN. But even so then all they have to do is "rate limit" you outbound. Since most people are websurfing, and reading e-mail. If you rate limited people to 10-15kb/s no one is really going to notice, URLs in the outbound packets are typicaly <200characters. e-mail with large attachments may take some time...
