Gawker's interface is mostly very straightforward and clean. The recording feature seems fine, like a simplified version of BTV Pro and more restrained than iVeZeen. It doesn't give you the same degree of control as an animation programme, such as Stop-Motion Studio but that is not it's purpose.
One of the nicest features, it seems to me, is the ability to combine inputs from two (or more?) cameras into one double width window. Very slick.
I haven't tested the Bonjour features so I can't comment. I was hoping to test the internet cam feature but cannot work out how to. There is no help facility and the web site is little more than an attractive brochure. I think that this feature needs to be made clearer for people like me who don't know what to do with "ports for sharing" or whatever.
