Based on a recent thread: https://premium.wpmudev.org/forums/topic/ip-trackingaccess-control-on-membership-plugin?replies=12 I wanted to put in a request for an integration plugin for WP Courseware (http://flyplugins.com/).
I've done a lot of research, and tried several different Learning Management Systems, and I've found Courseware is one of the easiest and most versatile. Problem is if you have more than course you have to manually add registered members to their desired course.
A recent upgrade added plugins to automate the connection between Magic Members, Wishlist, and S2 Member to WP Courseware so subscription type connects to specific courses.
None of these have full Multisite/ BuddyPress support, so it seems to me WPMU Membership fills a real need. All we need is a connection from subscriptions to courses.
