What do you mean temporary? Solutions 2, (some of the ones in 3), and 4 simply require additional devices or OS tags or categories to be added in their respective areas. Solution #1 is the only one I see really as a "temporary" solution. However, if you can think of something that would change that solutions 2-4 would not address, please - by all means say it and I/we can try make our solutions more dynamic.
