Could be interesting, but it reminds me a lot of WizIQ (although I do like the interface on Big Marker better):
Big Marker: “BigMarker is a free web conferencing community. Through our platform, you can reconnect with your family in Rio; manage your employees in Madagascar; organize your non-profit’s resources to Ottawa; teach a virtual class from Tulsa to students all over Thailand; foster a support group for cancer survivors from France to the Falkland Islands. With unlimited access to live events, there are endless opportunities for you, your community, organization, business, classroom, and social network to grow.”
