Avocent announced a device today which lets you wirelessly distribute HD content and is targeted primarily towards digital signage systems (though it looks to have in home uses as well). It is called the Avocent MPX1500T and it prices around $995.

The Avocent MPX1500T is used to push HD content wirelessly from a source to multiple destinations. The transmitter sports a DVI connector and, supporting both digital and analog video signals, can use DVI, HDMI or VGA signals.
