You have to remember that X10 transmitters are also signal suckers.  Both
transmitted and received signals on the "shared bus" powerstrip will be
attenuated, depending on how many transmitters are used.  The configuration
you suggest worked fine for one of the beta testers.  The number of
transmitters that can be shared will be a function how much load is
contributed by each one.

Sorry, but the XTB will never include a RF link.  But a future XTB may
include a direct powerline interface for one of Dave Houstons RF widgets.
