So what do you do when your ISP is throttling your BitTorrent traffic? Encrypt it, of course. Looks like the encryption of BitTorrent streams isn't just increasing in the US, & isn't only aimed at avoiding traffic slow-downs, either.

"Figures from a large UK ISP obtained by The Register show that the portion of BitTorrent traffic encrypted by file-sharers has risen 10-fold in the last 12 months, from four to 40 per cent."
