It is spelled Mikogo! (www.mikogo.com)
How does one write a review about a product and spell it's name wrong everywhere? Even the link is wrong! Anyway, it's spelled Mikogo (www.mikogo.com). Mikogo is the ONLY product I've found for which the free version is licensed for Business usage. (If there are others please let me know). Mikogo seems to be the only free option out there as a business which strives to stay legal on a limited budget. I must say it's pretty much a clone of GoToMeeting except it's free for businesses. As for restration, only the host needs to register, anyone invited to a meeting does not need to register. Just like GoToMeeting.
