Not really the forum to do so, as I am sure most wine enthusiasts are not interested in Linux or being able to watch the Olympics from their browsers, but…
For those running Gentoo (like myself) or any other Linux distro who are interested in watching the Olympics or other Silverlight 2.0+ content, do not try in Chrome, epiphany or other webkit browsers. However there is a beta plugin for firefox you can get here that so far is working for me in 64bit architecture with unusually high cpu usage, so results may vary. You may be forced to do like I have been doing which is using VMware workstation to watch. Good luck.
