I'm pilot testing Lightning Experience in my live production org and realized that I needed to be able to send URLs to my Classic colleagues. So I went and created a Lightning Component that will display the record ID as a Classy-friendly URL. You can do it too!

Thanks to @Katie McFadden for help in puzzling this out, @Ryan Ozimek and Soapbox Engage for publishing on their blog, and the Answers community for getting me the final few yards past the finish line.
