Unfortunately Skype for iPhone does not support initiating conference calls and it is also not possible to host or participate in a group video call.
Unfortunately for the problem you stated there is no solution with mobile Skype clients. If you wish to multicast an event to other parties then you need a PC or a Mac with Skype 5.x installed upon it, in order to make video calls.
you're complaining that a phillips screwdriver is unsuitable for flat head screws. grow up & use one of the many suitable technologies out there, such as ustream.
