shopping cart of the future

So, I am currently working on a multi-site shopping cart, that is URL friendly. That way if you were to have a cart it wouldnt be cart.php?cartid=12353456346&productid=3246346346346235246232346325 instead it is like /yoursite.com/products/HotDog. Now isn't that a crap load easier to remember. I think so, also works better for search engines. Thats all i am gonna tell of the project so far, as there is still a lot to develop and a lot that is a secret. I gotta tell you, when its done it will be a BAMF (bad ass mother f***er) ('thank you Dane Cook for that one'). With loads of stuff other subscription based carts don't have.
