Magento / Drupal integration API allows you to bypass Magento, using only Drupal as front-end.
It synchronizes everything : products, catalogue, prices, users. It creates orders and manages the cart.
Here Magento module for Drupal : http://www.drupal.org/project/magento
And here it's documentation : http://drupal.org/node/468036
Enjoy !
