SubEthaEdit: Collaborative text editing
SubEthaEdit is a powerful and lean text editor. And it's the only collaborative one you can actually use. By combining the ease of Bonjour with the world's best text collaboration engine, it makes working together not only possible but even fun...
SubEthaEdit uses Bonjour to announce its services on the subnet. Contrary to popular belief Bonjour does not provide collaboration services.
This is handled by an engine internally dubbed "Million Monkeys Framework" to ensure zero-latency, non-locking, constant editing of text.
SubEthaEdit's network protocol is based on open standards, namely the "Blocks Extensible Exchange Protocol" (BEEP).
