What are the bandwidth requirements of a mining rig?

How much bandwidth consumption can I expect per 900 Mhash/s rig (for instance) for both pooled and solo scenarios? I'm looking for a ballpark number for the on going requirements, after the initial blockchain download.

Quantity of traffic on test network

I want to begin experimenting with bitcoin. I notice the estimated upload traffic for the real bitcoin network is around 200 GB per month. That's too much for an experiment. How much traffic per month could I expect for a node on the test network?

How much internet traffic does a 3.5GH/sec pooled miner use?

The question is clear I think. I used 3.5GH/s because that's what the upcoming ButterflyLabs Jalapeno will run. Assume it's mining for an average mining pool with 3.5GH/s (only bitcoins). I'm interested in maintaining one on a spot where I can get…
