Shaw doesn't really enforce caps, it is up to you to honor the service agreement.
Nothing really would happen if you downloaded/uploaded 1600GB, the worst that may happen is that a few people from your node might come up complaining about their Internet being slow due to over saturation :P
Nothing right now. If you're on the bb50 and bb100 packages they want to make it so it automatically bumps you to the next package if you use too much bandwidth. They keep pushing the implementatin date for that back, so right now nothing happens.
I think the bandwidth tracker is out to lunch. It said I used less than 20gb's last month. I've done way more then that. Probably closer to 500gb. Since March 5th it says I've used .7gb's.. lol.
