Hi! I've been looking for such a tool as well. Lately digikam makers pulled together the DNG writer for their solution. However, you can very well use the HDRMerge tool and it's command-line interface to achieve good quality. I did some testing, and to me it looks like the DNGs produced with this combo are faster in Lightroom to load than those produced by Adobe.
As to my own motivation, I'm interested in getting the best possible results out of Sony A7, and currently the best results sharpness wise still come from TIFF files produced by ImageDataConverter. I hope the best result at some point will come from LibRaw. I will be switching to DNGs by LibRaw for performance now.
