I got a question off-list asking what UTFGrid is about, here are more

UTFGrid is way to encode feature attribute information to add 
interactivity in a tiled map environment (e.g. using mouse-over to 
display tooltips with attribute info on top of tiles). It was initially 
developed by MapBox devs for use with TileMIll and MBTiles.

Since a demo is worth a thousand words, see:


and for all the details, see the spec at:
