Yes, but I can't recall the reasons we discarded the idea. Something like this perhaps:

In general I like the idea of VPN as a utility - anonymous internet on tap. Utility-like services in functioning markets compete on price to the benefit of the consumer. On the other hand, things that look like one-dimensional utilities to the consumer isn't always. A service category where there's plenty of innovation potential left shouldn't pretend to be a utility. Especially players who aim to improve state-of-the-art. A pay-as-you-go model encourages consumers to compare quantities of something that is quite disconnected from the quality of what they get.

Paying per month makes more sense to me for another reason as well - It's similar to what we do with our suppliers.
