Yes, I can see that there is no need currently to open RAW files in 
hugin.

What I haven't managed to figure-out is a reasonable set of steps to 
get data from the camera, convert into a floating-point HDR format, 
process in hugin and convert from HDR to something viewable.

Apparently 16bit integer data isn't considered 'HDR', most 
applications that manipulate 16bit files just treat them as finer 
grained versions of 8bit data - These tools will generally do the 
wrong thing with the 16bit linear data as produced by dcraw (as they 
would with linear 8bit data).
