Room Tunes Still in Biz?

Anyone know if Michael Green's Room Tunes is still in business? (You know the guy who marketed his products with his picture.)

Their website (http://www.michaelgreenaudio.com/) has not worked for days and there's no info on the web that implies they've had recent business activities. Nor have I heard or read anything indicating that they are no longer in business. A real mystery. Thx for the info.
