With an off-the-shelf P4/3GHz and cheap BT878 boards we routinely grab 
and encode 2 streams at half-size, full 25fps (PAL), MPEG-1. 3x3 fps 
should be a piece of cake.

However, if you want audio, you usually need an audio baord per channel 
as well.

Also note: at 3 fps you could use one of these boards with 1 BT but 4 
switched inputs. Then the system could scale up to 16 or more channels.
