In fact, you can use exported resources (eg for auto-generating Nagios configs) without a Puppetmaster. You just need a database server.

There are arguments for using a Puppetmaster, and I cover some of them in the Puppet Beginner's Guide, but it's definitely not a requirement. The masterless setup that I describe in that book is in some ways preferable, and it's used in some quite substantial deployments (many hundreds of nodes).
