Sure, there are any number of coatings or additives in the glass that would
end up blocking RF signals.  I've got a sunroom that's practically a faraday

services greatly improve.

It's interesting to see echelon making noises again.  The fear of zigbee
must be pretty strong.  Is anyone making residential devices using echelon
stuff?
