Hi all,
  in the last couple of weeks I've worked on a patch to introduce
request classifiers in geom_io.c, I'm still sorting out some interface
issues with my mentor, but the patch is almost ready to go public.

I've started working on an md variation to emulate multiple disk drives
with a geom class.  By now it is only for our internal use, and it does
almost nothing, we'll try to integrate some hopefully useful emulation
feature into it.
