My main problem with this is that Spotify utilizes the full upstream bandwidth, causing the latency to go up dramatically on connections where the upstream is limited. If they were just a little bit intelligent and limited the streaming to 90% of the available bandwidth I'd be okay with it since that wouldn't affect the latency. Question: What is the best way to traffic shape all upstream connections on OS X? I've tried ipfw but I can't figure out a good way to e.g. limit the upload on all apps except for e.g. SSH.

If you have a recent (>=10.7) version, pf [0] is installed. pf is a more capable firewall than ipfw, and can shape upstream connections in a number of ways. As an example of what it can do, the Network Link Conditioner [1] is built using pf. The version in OS X is not the most recent version in OpenBSD, but that FAQ is a good start, and the man page [2] can fill in the details. 0: http://www.openbsd.org/faq/pf/ http://www.openbsd.org/faq/pf/ 1: http://mattgemmell.com/2011/07/25/network-link-conditioner-in-lion/ http://mattgemmell.com/2011/07/25/network-link-conditioner-i... 2: http://developer.apple.com/library/mac/#documentation/Darwin/Reference/ManPages/man5/pf.conf.5.html http://developer.apple.com/library/mac/#documentation/Darwin...
