a) There is _no_ way to identify a mobile decoder "on the layout" when the decoder does not support either Digitrax "Transponding" or "Railcom". By "on the layout" I mean "not on the programming track". This is a basic limitation of the NMRA standard-based DCC implementation, because the original NMRA standard does not allow "two-way" communication on the "main track".
