I would be very interested in this type of site. (I thought that it would be great for RemoteCentral to have a section devoted to .pdb files, but apparently we'll have to do it ourselves.)

I would like to see .pdb files subdivided by equipment (TV, VCR, DVD, etc.), by Brand name (Pioneer, Sony, etc.), a section for "Discrete IR Codes", and a section for a "Wish List" -- items that aren't yet on the site (including discrete IR codes.)
