skabus

What is it ?

skabus is a suite of programs and libraries for Unix systems that aim to implement a bus, i.e. a many-to-many interprocess communication mechanism.

It is very much a work in progress, and won't be complete for a long time. For now, it looks like a random collection of tools, even though there is a consistent vision behind them.
