zerorpc is a flexible RPC implementation based on zeromq and messagepack.
Service APIs exposed with zerorpc are called “zeroservices”.zerorpc can be used programmatically or from the command-line. It comes with a
convenient script, “zerorpc”, allowing to:
- expose Python modules without modifying a single line of code,
- call those modules remotely through the command line.
It looks like it used gevent for concurrency.
