Want info and feedback on use of Easy Webinar Plugin for WP on our multi-site

I've been watching a WP plugin called Easy Webinar for several years. It permits creation, etc. of webinars from a WP site with the Commercial license allowing it on unlimited sites (i.e. I assume all sites on a multi-sites platform).

I'd like to know the following:
1. Are you familiar with the plugin?
2. If so, your feedback on it will help us make a strategic decision on it's use on our neighborhoodboutiques.com site.

Thanks so much!

Linda
P.S. We LOVE WPMU. In fact, our marketing partner and designed is so enamored of it she purchased it and uses it for all her clients. Thought you'd like to know that!
