Drapes so the lip readers can't see you.
Make sure the drapes block IR. There are instances of even local police forces flooding the front of a house with IR light, and viewing the activities inside with IR viewers -- all of this through closed drapes. Or you could just put a nice incandescent light fixture between you and the drapes; nice IR output from those bulbs. Halogen fixtures ought to work also, but fluorescent bulbs don't produce enough IR. More importantly: attach a contact-speaker to each pane of glass, and feed Top 40 radio to it. There have been reported cases of spy types bouncing laser beams off windows and using the reflected beams to reproduce the vibrations produced in the glass by reflected sound; in other words, the window panes are large membranes which vibrate in sync with the sound that hits them, so you want to override those vibrations with something else. This reeks of paranoia, eh? Jazz
