Idea factory: Multiple streaming cameras at functions

I was thinking from the perspective of the wedding ceremony and reception...While there will definitely be a photographer

- I'd like people who could not physicall make it also be able to view

- Have multiple cameras and be able to view all the feeds at the same time (like say in a casino monitoring room).

It should be quite feasible since internet cameras can also be purshased for a price. However my idea is to do it with laptops having webcams stationed at vantage points, all of which are streaming their clips over the net. I wonder if there is an app that allows you to view multiple streaming clips simultaneously though.
