It's not really PHE as opposed to PE now, since it's not just the headers being encrypted. And yeah, it is better than BitComet's PHE since it is truly encrypted, and is designed more thoroughly (for example, there is no standard BitTorrent handshake for ISPs to detect and block). Also, it's an open extension, unlike BitComet's, so has the potential to be adopted more widely. I'd think that the spec (I'm assuming you mean spec, since the algorithm is just RC4 encryption, which is supposed to be easy to implement) is at least close to final (if it isn't already), since it's already implemented in the betas for both µTorrent and Azureus. And I guess that's what the beta is for -- to test if it is working properly, and to see whether any changes need to be made before an official non-beta release. @ML: Heh technically if you're not getting your peer list from any other client, then your only other source in a private torrent is the tracker (unless you manually add an outside peer yourself, but we'll discount that in this case), so that's why I said that. And yes, what you wrote in that first line was what I was trying to get at (only in a much more verbose manner xD).
