Described herein is an implementation of an inter-process communications technology. One or more implementations, described herein, facilitate creation of a bi-directional message conduit having exactly two endpoints. A first endpoint is owned by a first software process and a second endpoint is owned by a second software process. One or more implementations, described herein, maintain the bi-directional message conduit for passing multiple messages via the bi-directional message conduit from the first process to the second process, according to established rules that can be checked.
