Progressive Enhancement for the Mobile Web

Details
This month, Brad Frost (http://bradfrostweb.com/) and Jack Bishop (http://interwebjack.com/) of R/GA (http://www.rga.com/) are talking about Progressive Enhancement for mobile, something I saw them present on at CapitolJS:
The mobile web is full of constraints, fragmentation and bugs. Despite these hurdles, the mobile web offers some extraordinary opportunities to create great user experiences. We'll cover some important-yet-tricky mobile web development techniques like fixed positioning, geolocation, touch events, network detection and offline access. Hopefully you'll walk away knowing what to consider/look out for when creating mobile web experiences.
Plus some room for lightning talks and, of course, drinking. Looking forward to seeing you all!
