Okay, I've started on this and have the OpenLayers.Control.CacheWrite.cache part working (tiles are getting cached to the Web SQL DB), but I think I've run into a problem with the OpenLayers.Control.CacheRead.fetch method. I'm not quite sure what's happening, but it appears that the fetch method needs to complete synchronously for the dataURL it supplies to be used as the image src. Does that sound right? If so, I think I'm dead in the water.

Subject: [OpenLayers-Dev] CacheRead and CacheWrite with Web SQL Storage?
Hi, OpenLayers developers. This is my first email; I hope I'm posting this to the proper list.
I'm interested in the work done here:
The pull request says that "even asynchronous backends could be added." By any chance, is anyone working on Web SQL Storage version or the mentioned pluggable version with multiple backends? I need such a thing for my current project, so I'll probably try if no one else is already doing it. If I get something working that's sufficiently generic, I'll submit it as a patch.
