Gale is a messaging system resembling Zephyr in UI and social characteristics, but IRC in architecture, with some features of its own. It supports the use of public-key cryptography for privacy and authentication. It has a spanning-tree topology with failover, little server state, no concept of "op privileges", security through end-to-end encryption, multi-line messages, and command-line-driven clients, and directed categories, which prevents unnecessary distribution of messages.
