It doesn't get much easier than this.
Macromedia has added a training module and a virtual classroom to its Breeze platform.
The live module is the equivalent of Centra or WebEx, including a webcam capability, application sharing, automatic capturing and publishing, and the usual controls. The training module adds course creation, learner registration, self-enrollment, quizzes and surveys, and tracking.

Add all this together and you get a hosted solution that includes a simple learning management system and requires no programming.

If I were short on time but had money in my pocket, I'd be tempted to implement an entire eLearning infrastructure on Breeze.
Caution: That's my enthusiasm for what's described at Macromedia's website. I don't know what Breeze costs or how well it scales, nor have I had the opportunity to kick the tires.
If their product is as good as their vision is clear, Macromedia is destined to become an eLearning powerhouse.
