Streaming Recording Broadcasting: camera that records a live event at the same time

Hello,

I would like to set up a camera that records a live event at the same time, streaming it to my website, and then saves it so I can post it to my website archive.

For streaming, I was thinking about doing stickam or justintv, would I be able to somehow setup my camera to stream via those services?

Also i'm assuming I'd have to record to the camera hardrive and then import it into my computer and then upload to the server. Is that the only option?

Thank you
