If you try to mount a ShowOff deck under a path with Rack::URLMap, that paths to the assets are not correct. I've added @asset_path to a few places to make sure decks load correctly if you want to host multiple decks on one domain.
Make it possible to run ShowOff apps under Rack::Map.

Make ShowOff compatible with Rack::URLMap
Something seems off here on ruby 1.9.2 and 0ea1df5. asset_path is coming out as an empty string and File.join('', 'a') is /a not ./a. What was this gsubbing supposed to do?
