Thanks for the help again on the Shoulda questions last night guys.
I finished up the testing of the plugin so I'd love to hear some of your thoughts:
http://github.com/tcocca/wkhtmltopdf_on_rails
Again it uses the wkhtmltopdf library (
http://github.com/antialize/wkhtmltopdf ) to generate pdfs in a rails app. It works as an ActionController mixin or you can just use the class in the plugin straight up.
The README is pretty decent.
