There are a few online meeting / webinar / live learning tools out there. Alternativeto for example lists a few: http://alternativeto.net/tag/video-conferencing/
But also there's opportunity for easier solutions...
I know a few of them but I like the concept of involving the user before even building it.
Well, when looking at all the tools that are out there, I really miss features that are targeted at charging for webinars. Submitted my feedback and hope that this becomes a reality!
