Noiptun is a client-server based application that allows secure communication with computers that do not have an IP address. It was started as an effort to port the control functionality of Hogwash to the newest version, but grew into its own project since it doesn't need Hogwash to function. It is being developed and currently runs on Gentoo 1.4 and Red Hat 9, although it should with a bit of work compile on any *nix with support for tun devices, libnet, libpcap, and OpenSSL.
Flexmock is a mock/stub/spy library for Python. Its API is inspired by a Ruby library of the same name. However, it is not a goal of Python Flexmock to be a clone of the Ruby version. Instead, the focus is on providing full support for testing Python programs and making the creation of fake objects as unobtrusive as possible. Flexmocks design focuses on simplicity and intuitiveness. This means that the API is as lean as possible, though a few convenient short-hand methods are provided to aid brevity and readability. Flexmock declarations are structured to read more like English sentences than API calls, and it is possible to chain them together in any order to achieve high degree of expressiveness in a single line of code.
