Use e-Commerce for paid membership?

Hey Folks;

I'm in a bind with a project that was passed to me late and am trying to find a good CMS that can have a paid membership through authorize.net. I have been playing with Drupal and am liking it a lot and came across e-Commerce as the module for handling integration with authorize.net. However, I don't see any info on whether it can be used to handle paid membership.

If anyone has any insight on this, yay or nay, I'd be greatly appreciative.

Thanks,

Michael Cooper
