What's that sci-fi book where phones are dropped from orbit? People are able to ask for things which are then manufactured and delivered to them. I think the scheme is used to bring down an oppressive government. I read this book a few years ago, and now I'm looking for more by this author.
Singularity Sky by Charles Stross. There's a direct sequel, Iron Sunrise, and Stross has been a fairly prolific author over the past decade, with a number of ongoing series. His best known work is probably Accelerando.
