I agree that it potentially can be a great benefit;  but it could also be a
problem.  Please could you let us know about:

  - Does the LVM framework provide a practical means of linking it
    into GRUB (not just the user part, also the freestanding code)?

  - Is its license compatible with the GPL (version 3)?

  - Will it increase the size of our lvm.mod?  Size is critical here, because
    it's highly desireable that lvm.mod fits in core.img which fits in
    the post-mbr region.

Thanks
