Theodore, since you probably know this from at least one side of the
equation; how difficult do you think it would be to simply fix this in the
ext2 EVMS plugin? In other words, how much work is there to

  a) Determine if a file system is online resizeable, and
  b) Resize it using the right ioctls

Actually, b) could probably simply be handled by calling resize2fs like with
offline resizing, but I'm not sure how one could detect if the user had a
version capable of doing online resizing.
