What Do I Need?

A video camera (digital with fire wire is best)
A computer (a laptop with fire wire is best)
A high speed Internet connection.
Also any necessary cables to connect all of your equipment.

Yeah, I'm sure most of my chruch venues won't have a problem with somebody stringing all this crap up. Not to mention the broadband link.
