あらゆるサイトでオフライン編集が可能になるgearsmonkey
理論的にあらゆるサイトでオフライン編集ができるgearsmonkey。firefox、greasemonkeyとgoogleのオフラインツールgearsの組み合わせで動作する。もともとwikipediaをオフライン編集するためのユーザースクリプトだが、javascriptに詳しい人であれば自分の好きなサイト向けにスクリプトを改編してgearsを使ったアクセスができるようになる。
But alas, if only it were a reality that every site was Gears enabled -- the internet faster and available anywhere. You'd need every site to implement Gears -- GearsMonkey to the rescue! By using Google Gears with the Firefox Greasemonkey plugin, you can inject Gears code into any website that you want. Don't wait for your favorite website to enable offline support -- do it yourself.

Even better, the author of the script provides a howto guide for taking virtually any web site offline with Gears and Greasemonkey, so anyone with some javascript chops should be able to start building Gears access for their favorite sites (here's hoping we see a lot more of these).
