I have an idea of a service that will allow users to subscribe blogs updates and receive them by regular mail.
Here's how it works:
1) a blog owner registers his RSS feed, set price, how often updates are issued and other parameters. After registration he gets HTML code of a button that he needs to insert into his blog.
2) a blog reader can click this "subscribe a hard copy" button on the blog. He will be transfered to the subscription page, where he fills in his address, credit card info and so on. After this he will be receiving a printed copy of new posts from this blog biweekly. It will be a booklet with 15-20 pages of legal size.
The blog owners will then receive what user payed for the subscription minus some small fee for the service.
A blog owner is free to set any price for his content assuming that printing and mailing of one booklet is about $1.
