I actually do wish that telecos would introduce metered plans, providing that current prices aren't used to set the lowest rate :)
The "mobile broadband" plans charge $50 (or even $100)/gig overage. These are the plans required for tethering-like services.
"5 GB overage rate is $0.05/MB and 250 MB overage rate is $0.10/MB"

The "Voice and Email" plans seem to be the ones required for Droid:

"Anyone using more than 5 GB per line in a given month is presumed to be using the service in a manner prohibited above, and we reserve the right to immediately terminate the service of any such person without notice"
Ok, so there's no data overage charge, but Verizon has the right to suspend your account.
This is yet another example of how confusing terms prevent sales. Compare the complexity of Verizon's offerings to Twilio's pricing page:

I'm not a Twilio customer, but I probably would be if I had a need. Perhaps Verizon believes that confusion allows for better price discrimination?
When I click "My Services" and "My Plan" I have "Email And Web For Smartphone" which says unlimited when clicked on. Also, under "Overview" -> "Cell Usage" -> "Data" it says "Monthly access: unlimited." I think you're OK.
For my Droid, I have the "email and web for smartphone" plan ($30). I also have a separate wireless broadband card and plan ($60). When I look at my account on Verizon's web site, I see a data cap of "5GB" for my broadband card and a data cap of "unlimited" for my Droid.
