I've only tried network rendering with Vue, but based on my experiences there I would say that you would be wasting your time - both in terms of setting it up, and in terms of render time.

I've networked a Core 2 Quad machine with a P4 3.4 GHZ machine - it was slower than just rendering on the Quad core machine alone - probably due to the extra time needed to send the render data across the network and the P4 machine still rendering its part when the other machine had finished all the other tiles.

I was recently able to network an i7 machine with the older Core 2 Quad - this made a real difference to render times.

I'm pretty sure that rendering on a bunch of Atom CPU's will be a LOT slower than on any modern CPU.  The AMD 6-core processors are a reasonable price, and there are still Intel quad-core machines available for very reasonable prices.
