Authorize.net ARB Integration with Virtuemart

We sell skin care products on our website, using Virtuemart and Authorize.net. We need to integrate [login to view URL]'s ARB program into Virtuemart, in order to give our regular customers the option to have their products automatically billed and shipped every 1-3 months. Not all products will be available for Auto-Renewal. It is important that users can purchase both Auto-Renewing products and standard (non-auto-renewing) products at the same time. On the front end, we want users to clearly see which products are available for Auto-Renewal and select which products they want to Auto-Renew. We also need users to be able to log in and manage their subscriptions (cancel, update, etc). We already have users creating accounts via Virtuemart; we'd like the subscription management to be linked to the same account. On the back end, we need to be able to easily manage the subscriptions. We need to be able to select which products are available for auto-renewal. We also need to be able to manage users who are using auto-renewal, and we need to be notified every time a product is automatically renewed, so that we know what needs to be shipped and to who it needs to be shipped.
