I suggest you search for something along the lines to what you linked to, but however it obviously needs to be IR based. Whether or not they make them...I don't know. What I can tell you is the prospect of using a X10 module & IR543 would be considerably more costly. X10 isn't all that reliable to begin with.
edit:
Try searching through
www.xantech.com. They manufacture many IR contact closure options.
