For those Google Chrome users who need access to one or two Silverlight sites, a Microsoft developer offers a file-tweaking work-around to get access to certain sites.
The Chrome/Silverlight hack requires grabbing a few .js files normally intended for Silverlight developers and tweaking them to have Silverlight sites accept and provide content to Chrome. By downloading the .js files and modifying them a bit, you should be able to access, as the developer rates it, "most" Silverlight apps, but your mileage will certainly vary.
