It seems I didn't get Bill's mail, but FWIW it may be interesting that 
this DMFS and probably a lot of other goodies that were developed at 
NASA/Ames are actually available in othersrc:

 	cvs -d anoncvs@anoncvs.netbsd.org:/cvsroot co othersrc/nastore

You probably want to have a look at othersrc/nastore/kern/dmfs and the 
associated tools in .../kern/sbin/*_dmfs.
