Actually, they can be configured to acknowledge a command (or any state
change).  I've never needed this feature because (a) I don't have the
reliability problems you are worried about and (b) my use for 2-way
functionality is generally to see in what state some other person/process
has left the device--something that is usually best done at the moment I
want the information.  You might want to take a look at X10's extended
command set; it is quite complete.
