I see that awesomecomplete is integrated, and custom, on the checkout template. I have a client who needs to integrate http://www.pcapredict.com/
into checkout. I'd like to be able to use the existing script, but before I go digging/hacking, I'd love a sense check. Is this a good idea to try to tie into your implementation? Or would I be better of using something like twitter typeahead to avoid conflicts?
