So I finally gave something back. Granted, in proportion to how I've benefitted from open source software over the years, it's not much. But it's (marginally) better than nothing, right?
This happens to be the module with the widest potential appeal, since I can't imagine too many people are interested in modules that interface with proprietary registration systems, or with non-mainstream, non-public video vendors. (Randy's Location Ads module rocked, but there's no way that's ever going to be ported to Drupal 5.x or 6.x)
Basically, it lets you attach Drupal as a commenting solution to any sort of foreign content management system.
Embarrassing, but they were fixed with some help from the CVS guru at Drupal.org.
