James, SPDIF is a 75 ohm coax signal so it can be run on video cable such as RG-59 - if you terminate at wall panels using BNC panel mounts, you can use it for either SPDIF or a camera. For SPDIF you'd need an adapter from BNC to RCA, available at Radio Shack or at REAL electronics stores
IF you ever plan to use several digital devices, you may want to consider word clock distribution - for a few closely spaced devices, it's OK to "daisy chain" the WC signal but for more than a few feet, it will drive you nuts trying to phase sync your sound - better to use a common clock fed into a distribution amp, and ALL outputs of that DA should have the same length coax or you'll get minute phase shifts between channels that'll mess up stereo imaging, cause comb filtering, etc...

Soooo, when a Musician dies, do they hear the white noise at the end of the tunnel??!? Hmmmm...
