Does anyone have any experience of ISPs that offer larger data caps in return for filtering? I used http://www.telme.org.nz to search for a new ISP and the ones with the largest data caps also have traffic filtering. Slingshot, for instance, prioritises traffic in the following order (from http://www.slingshot.co.nz/popupspeedinfo):
1. VOIP 
2. Gaming 
3. Browsing 
4. Streaming 
5. Local traffic
6. File sharing, including Peer-to-Peer (P2P)

What does this mean in real terms? Are videos slow to load? When I use P2P for completely legitimate reasons (e.g. downloading game patches) is it incredibly slow?

Thanks.
