Tuco10,
Are you wanting to use your E-Z Command controller to operate your snap switches? If you are I don't believe it will.
I *think* you need a DCC decoder attached to each switch. Someone here will be on me ike a duck on a June bug if I'm wrong and giving you wrong information. I have the E-Z Command and the Dynamis Wireless controller (not together on one track) for my DCC control. I'm sure the Dynamis is capable of operating your switches but I don't know if the E-Z Command is.
If you are going to wire your switch machines and mount the SPST switches in a bank or control panel and operate them by hand you'll be ok.
I'm going through the same thing with the layout I've been working on for a long time now. I'm using Atlas code 83 track but am going to use my Dynamis to control both my trains and switches on the turnouts. With the advice of some people here I chose to use Digitrax DS64 4-switch decoders ( http://www.digitrax.com/prd_statdec_ds64.php ), Atlas Custom-Line turnouts and Atlas Remote Switch machines. ( http://www.atlasrr.com/Trackmisc/hocode83.htm )
Happy Rails
