Maybe we should start from raw ca?As far as I remember, FNAL version of EPICS-Python interface uses SWIG(Simple Wrapper Interface Generator). It maps C/C++ API interface into Python API. KEK version of EPICS-Python interface was written from scratch, and it also maps C APIC for EPICS CA to Python API, but not all. You can build your own Python module to hide the raw CA API, which may work similar to EZCA. Most of Python application in KEKB uses Tkinter(Tcl/Tk widget interface for Python) and EPICS CA. And the most of channels in these applications are monitored, so that no need to wait fixed pend-io time. If user likes to use Python-equivalent of a raw CA API, it is also possible.
