Does ActiveMerchant support subscription-based transaction?

I am trying to integrate ActiveMerchant in my rails application. I have specific plans for what if a user has a user access limit. As you all guyz, you probably know what a subscription based app is, I will not explain my app. Please offer me some examples for this. I already watched episodes from railscasts from 141 to 146, but Ryan showed only Paypal Web Payments Standard and Paypal Web Payments Pro. I also read a bunch of blogs, but that didn't help.

Please, help.

Thanks at Advance.
