We’ve just released initial version of two gems: Hashbang will (almost) transparently enable Google indexing for your AJAXified pages. And it’s based on Sunscraper which is WebKit AJAX crawler binding.

Sunscraper is still RC and requires Qt to compile.

We had plans to convert Sunscraper to complete WebKit-only binding (to replace watir and all existing broken Qt bindings) to give Ruby full-featured headless browser support. If you need it please let us know so we finally decide if we should ;).
