That's one my list of things I'd like to do, but my Perl isn't strong
enough yet. :(

There's been some discussion about it in the past on webkit-dev. I
tables to store properties. It's important that runtime disabled
properties are completely disabled (e.g., "webkitIndexedDB" in window
returns false). If you're able to get it to work, that's great!
