I watched a couple TV episodes with the Netflix Android app. A 26 min 47 second episode clocked in at 96.8 MB. That's a 493 kbps bitrate.
If 100 MB can last you a full episode on Netflix, I don't think Mobilicity users intending to watch Netflix on the go have anything to worry about. Stream away. Bittorent will probably be slow as hell or not work with their traffic management policies though.
As for Netflix at home, the lowest quality setting consumes approximately 0.3 GB per hour. That's 76.8 MB/15 min so you're fine there too.
You just can't stream with anything more than the lowest setting on your laptop though. The medium setting is 0.7 GB/hour. The high 1 GB/hour. And the HD was 2.3 GB/hour last I checked. But apparently they reduced data consumption for HD (with this new compression techonology they are using, it might consume less data now).
