[SGVHAK] Using JMRI or CMRI to access hundreds of I/O lines

I don't know.  Call my cell number or just show up some Wednesday between 7 and 9 pm.

>> Anyone on list using JMRI or CMRI for model railroading or any thoughts on being able to access hundreds of I/O lines?  I need to be able to read and write to a crazy number of I/O lines for doing block detection, block control, switches, signal lights, track configuration for switch yards and routes, etc.

One or more arduino's or possibly Raspberry Pi's for the low level functions like signal lighting, crossing gates and possibly setup track control.  Then run JMRI on a laptop or possibly Raspberry Pi as well, for high level functions like Central Traffic Control for routing, etc.
