hi. i am developing a store for a band. a company that does merch is building the store with

commerce, hosting it on their end, database and all. the store i am creating has a customized look different from the templates that their store uses. i have save the URL of the forum post that describes how to remotely host an item. one form per item, etc. but how do i remotely host the shopping cart? so this way i can have the store on the band's servers, yet all the info and store pulls from the database/store hosted on the merch company's site?
