Here's my final pipeline. Now I just need a supercomputer or two to help speed up regenerating all of the photos on my site that have raw files..

dcraw -c -w -H 0 -o 1 xxxxxxxx.cr2 | convert ppm:- -sigmoidal-contrast 3x50% -sharpen 0x1.2 ppm:- | cjpeg -quality 97 -optimize -progressive > xxxxxxxx.jpg

Cheers
