Neither the small computation or a email stamp purchase are the brain childs of microsoft. However this idea is gaining mind share because the redmond machine has put its weight behind it.
I think the government might like the idea of email postage, since it would serve as an entry point into the taxation of email. Plus a systematic government postage system could underpin email tracking, since postage key (stamp) and key checking would probably not be anonymous.
Even if a national email postage system is used, I don't think everybody would use it, since it would be hard to stuff the free email cat back in the bag. There might be two systems, where you only allow free email from known friends and family, but use the postage system when going outside of known sources.
As I read it, it's not about revenue, it's about bandwidth. This is the same idea as parking meters. Meters don't yield a lot of revenue -- they're designed to keep parking spots on city streets turning over.

If microsoft servers became the e-postmaster for this email postage system I wouldn't support it. I assumed the final spec would be governed/controlled by an entity like ICANN (which oversee the domain name system).

Yes, wool socks are better than cotton but; battery powered heated socks are even better. And yet our feet end up cold at some point anyways. When we are hunting we are usally trying to be as still as possible, for as long as possible. The problem is, when we aren't moving, our blood circulation slows down. We especially lose...
