How can I integrate Magento in a site? Does anyone know of a way to integrate Drupal 7 with Magento?

I see that the Magento module doesn't have a version for Drupal 7, but I'd like to keep my Drupal installation shiny and new at the start of the project. I'm talking to the powers that be about using the commerce module instead, but I suspect that's going to be a non-starter.
The easiest and simplest way to integrate drupal with magento is using magento API. http://www.magentocommerce.com/api/soap/introduction.html. Magento API provides all the functions necessary for e-commerce operation. You can get the list of all categories, products, product reviews, shopping cart feature etc.
