Cash for Cache

I remember seeing an idea posted here recently about making one's cached page content available for Bluetooth users who want to access the web in areas without free WiFi access. I cannot recall the title of the idea, nor the identity of the poster, but if I recall correctly, the idea was basically for folks with Bluetooth-enabled devices such as laptops or smartphones to be able to access the cached browser history of nearby Bluetooth-enabled devices.

Well, my idea is similar, but not quite so altruistic. My idea is to make one's cached page content available, but for a charge. I'm thinking a per-kilobyte or per-megabyte charge, but significantly cheaper than cellphone carriers' pay-per-use rates, which are usually around 1 cent per kilobyte or 2 dollars per megabyte (yes, there's a difference, it depends on which carrier it is). In the last 2 weeks, I've used nearly 160 MB just on my phone, which is why I don't mind paying 24.99 for the Unlimited Data / Messaging feature offered by my carrier, but I digress.

Using a credit card system such as Google Checkout (maybe not, I don't know much about payment systems) and a simple data transfer rate measuring application, one could have Bluetooth always on, and other nearby users could synch with your laptop or smartphone, send their credit card info to your computer (or whatever 3rd party system you use) for validation, and view access your browser history, and you charge them depending on the amount of data transmitted from your computer to theirs. You could charge a very miniscule amount, but it would add money to your wallet in a trickle effect, and doesn't cost you anything in return.
