As John D replied, there is no 'NMRAnet CAN bus standard.' While John is an advocate of the 'openLCB' protocol, he did mention CBUS which is an alternative scheme which is well tried and tested. This has been developed (before openLCB existed) in conjunction with MERG (Model Railway Electronics Group) which is an international organisation devoted to the promotion and development of electronics for Railway Modelling. CBUS is also based on CAN but uses a different approach and protocol to openLCB. A full range of kits for modules and DCC control is available to MERG members. Basic information is available from the main MERG website but we have a Yahoo group (mergcbus) with a lot more information. CBUS is fully supported in JMRI and other groups and commercial organisations have software that can be used with it. Like openLCB, CBUS is an 'open' standard available for anyone to use.
CBUS is in regular use on many layouts and your questions have been implemented by many users who could advise you.

CBUS is one of two proposals for a NMRAnet. No decisions have been reached yet.
