After checking with Verizon on their mobile Hotspot plans, it isn't feasible. However, I can do it through my unlimited data plan for my iPhone. 3G is faster than the Road Runner service I have.

If I use the IPhone, I can use a USB connection. My centos machine acts as my firewall/gateway on my wired network so the question now is, if I use the USB connection to my centos machine will that bypass the firewall?
