One of the most common questions/comments I get is "Won't this all be wireless eventually?" This is a reasonable assumption.  Many items that used to be wired - phones, internet, possibly Cable TV, are now recieved without wires. 

No, you will not be able to abandon wired infrastructure in your new home.

Why?

HDMI. High Definition Multimedia Interface sends video over uncompress, full-bandwidth links along with encrypted keys to make sure the sender and reciever are authorized.  The key is uncompressed. The latest spec (1.3) calls for up to a 6.8GB information stream (synchronous). This won't run over wireless - it won't even run over 10G wired ethernet.  HDTV through the air and over cable lines is compressed but the compression technology is not symetrical - it's very,  very expensive to compress.  Also, recompressing previously compressed content causes quite a few quality problems.  Lossy compression is how those cool UWB HDMI demos are working now.

2 Cat5's to each video location will support HDMI.  We don't believe wireless will support full bandwidth encrypted HD content in the foreseeable future.
