Nope. Still an annoying process to stream YouTube, and it still chops. The general vibe of the Tor community is to not use up excess bandwidth unless you have to, because it chokes endpoints and gateways and leaves less room for others. I think a lot of gateways probably run some form of bandwidth limiter, but that's just speculation. It's considered extremely bad taste to do things such as high-volume P2P
I had always assumed that the P2P was to help mitigate the cost of data so that the Spotify team could better use their limited (at the time) funds to secure more music contracts. Were operational costs not as drastic as I might be assuming?
