Free tethering possible?

[Vret]

I did a few searches, but there was just so much information to sort through I couldn't find what I was looking for. I'm running OMJ's custom Verizon ROM, and I have Windows Vista Premium as my OS. I'm looking for a way to hopefully use the Internet Connection Sharing, but via bluetooth. I'm trying to avoid the additional fees Verizon tacks on for using the phone as a modem.

Can anyone help or at least point me in the right direction? Thanks in advance.
