Felipe's been working very hard and the latest release (1.3.2) is fantastic!

To wit: an ephemeral nymserv client based on the Zax-style nymserv. The client also incorporates end-to-end encryption and signatures using GPG if desired. Here's a link to some documentation.

To install, sudo pip install nymphemeral should do it. To upgrade, sudo pip install nymphemeral --upgrade. Source code for nymphemeral is also available.
