What type of product, hardware, software or another type of product?
My understanding is the Lesson Module can be interactive.
I use Moodle to post training sessions, announcements, and to run a certification track for a network of dealers/distributors. For a new product release or enhancement I post an announcement and any related documentation (brochure, product bulletin, userguide…).
I use a forum to send out a broadcast e-mail to announce the new item. After a few days I go back and check on how many students signed up for the session.
Yes Moodle will work for you.
I use a combination of Tech Smiths, Camtasia and Adobe Captivate to create sessions. It depends on what I'm doing at the time.
