So if you do have a look at Rails be sure to hang out in #rubyonrails to get up to speed quickly and share tips with other railers. I'm also just on the verge of implementing a nice PayPal IPN wrapper for Rails as I'm using PayPal myself for a new project. I've been thinking about releasing the Authorize.net wrapper that we used for Basecamp as well. Anyway, lots of choices for doing what you're looking for in Ruby. Beside the options that Kirk mentioned, there's also Borges, which uses that cool continuations stuff. I don't know if it's yet in a state that you want to base a production app on, but their highlight example is exactly a checkout processs for a shop. -- David Heinemeier Hansson, http://www.rubyonrails.org/ -- Web-application framework for Ruby http://www.instiki.org/ -- A No-Step-Three Wiki in Ruby http://www.basecamphq.com/ -- Web-based Project Management http://www.loudthinking.com/ -- Broadcasting Brain http://www.nextangle.com/ -- Development & Consulting Services
