Streaming DJ Sets

I currently have a website set up using livestream with i use to broadcast live mixing of local DJs. At the moment i'm stuck to using one webcam per PC/laptop. I was wondering if anyone had any suggestions or alternative streaming services that could offer me more webcams.. been looking at some djsound videos on you tube and like the idea of having a webcam looking down onto the equipment and another showing us from another angle.. i can then switch between the two as and when required... anyone have any experience of this? ohh the website is www.beatlab.tv

TIA
Matt
