ZeroMQ is an emerging message oriented middleware architecture that is being increasingly adopted in the software engineering of distributed control and data acquisition systems within the accelerator community. The rich array of built-in core messaging patterns may, however, be equally applied to within the domain of high-level applications, where the seamless integration of accelerator models and message logging capabilities, respectively serve to extend the effectiveness of beam dynamics applications and allow for their monitoring. Various advanced patterns that include intermediaries and proxies further provide for reliable service-oriented brokers, as may be required in real-world operations. A report on an investigation into ZeroMQ's suitability for integrating key distributed components into high-level applications, and the experience gained, are presented.

CAFE (Channel Access interFacE) is a C++ client library that offers a comprehensive and easy-to-use Channel Access (CA) interface to the Experimental Physics and Industrial Control System (EPICS). The code base has undergone significant refactoring to make the internal structure more comprehensible and easier to interpret, and further methods have been implemented to increase its flexibility in readiness to serve as the CA host in fourth-generation and scripting languages for use at the SwissFEL, Switzerland's X-ray Free-Electron Laser facility. A number of specific design features are presented, including policies that provide control over configurable components that govern the behaviour of interactions, and the methodology that guarantees that the outcome of all remote method invocations are captured with integrity in every eventuality, thereby ensuring reliability and stability. An account is also given on newly created bindings for the Cython programming language, which offers a major performance improvement to Python developers, and on an update to CAFE's MATLAB Executable (MEX) file.
