 	It's complicated.  My housemate (also house-owner) is a superlative 
neat-freak.  There will be no wires in the hardwood, glass, and leather 
furniture room.  I have played with wireless and it's promising.

 	I'm doing 2-pass, so 4hr/hr would be about right.  It's avidemux, 
HQ denoising, resizing, no deinterlacing.
