All in all i would recommend keeping track of your useage under verizon still just to prevent them going into panic mode.
PdaNet is great if you dont wanna pay an additional $15 a month just to tether your phone and of course have unlimited data package on your phone.
I have no idea if they will enforce anything on the phone's data useage.
Maybe someday (4G) we will all be able to have truley unlimited access again.
