Well I just got off the phone with Verizon Wireless tech support.
It turns out that if you talk at someone enough and sound smart enough they will come around to your way of thinking.
After looking at the Dun-hack on this site I read my contract carefully. It turns out that you DO have the legal right to teather your phone to your laptop, provided you don't do anything illegal with it.
I have requested that the represenative review and discuss this issue further with people in the company who are more in the know and may be able to shed further light on my question about teathering.
It appears that since you are using 3rd party software with the phone as the modem and the unlimited data usage plan is in effect there will be no additional charges for using my phone as a modem for my laptop.
How about them apples?
Anywho, I'm going to refrain from stating that this is a final answer until I have written confirmation either via email or paper.
