Webinars for iPhone?

Now that the first wave of iPhone applications has basically hit, I’m anxious to see what the next wave brings. One application that I would like to see would be the ability to attend webinars from the iPhone.

Someone like WebEx or Citrix (GoToWebinar) would be the natural choice to develop this. As an attendee, you could call in on the phone and then view a shared screen, allowing you to zoom in for details. And add the chat window to complete the experience. I could see this requiring 3G or Wi-Fi access for speed reasons.

I would see this as a free application, since the goal is for attendees to participate from a mobile platform.

Does this make sense to you? Post your thoughts in the comments.
