Zeno-He (zhe for short) is a compact implementation of the Zenoh protocol that does not depend on dynamic allocation or threading. Instead, it is a non-blocking implementation that assumes single threaded use with polling, and a system that can be sized at compile time. Zhe can be configured to operate in peer-to-peer mode or to operate as a client that relies on a broker. Targeted configurations vary from a minimal client on an Arduino Uno (an 8-bit CPU with only 2kB of RAM) to a bunch of low-power, high-integrity CPUs running a real-time, distributed control system, and on to dozens of peers running on high-end CPUs and saturating a fast network. Whether it will actually meet all these requirements remains to be seen. Still, so far, so good.
