Why don't you use proxy images? 
Keep your digital originals separate, back them up (to a normally unmounted or 
read-only drive), and run a script to convert them to smaller Jpeg 'proxies'. 
Then you can use those proxy images for cataloging and browsing. It's a lot 
faster than cataloging or browsing RAW files on any system. Also 100% safe, 
unless you botch the backup step.

I also use small 'scriptlets' which I associate with my .JPG files. These 
scripts can pick up a copy of the original to work on, should I so desire. My 
right-click menu in Digikam contains descriptive entries like; "Copy Jpeg to 
PDA", "NEF 2 UFRAW", "NEF 2 GIMP", "TRASH Jpeg AND NEF", "10x15","Copy 2 
Output". These are all links to small scripts that perform their respective 
tasks very conveniently. 

This means I can have 100% secure originals if I want (by not letting DigiKam 
index the directory where they are stored), and the speed, indexing and 
off-line access that relatively small .JPEGs give me. 

I'd love it if all this was incorporated in DigiKam, but for now I'm quite 
happy with my setup the way it is. Perhaps this approach could be the 
solution you are looking for.
