Why not make your URLs responsive?
responsiveurl.co.uk
responsiveurl.co.uk
It automatically extracts the title of the current page and appends it to the URL, like so:

Edit: I should have said "...of exactly how search algorithms work..."
It isn't that far fetched though, using canonical meta tags you can preserve the main your links on search engines (so you don't SEO ruin yourself).
Most sites have multiple ways to access the same articles/content... no reason not to use a simplified version of this for mobile access. What I mean is, when a mobile is detected use simplified/shortened URLs. Helps if you are copying or manually entering URLs in texts etc...
