Imagine you are connected to a good peer (i.e., one that sends DATA back). If the good peer sends you a CHOKE, you immediately know that he is not going to respond anymore and you should look for a different peer to download from.

What's > more, it makes the draft better structured. I personally see two issues. First, it means content integrity isn't discussed before we present the protocol options and UDP encapsulation. Second, the Security Considerations section will become roughly 20 pages out of a 47 total which sounds a bit unbalanced to me. But you have more experience in this than I, so please let me know what is common. CU, Arno
