  I started to read the paper then it turned into a skim.  I don't like this
method much for this generation of games and I also think that its old.
Didn't Tribes use something like this?  The sample data that is used is
close to best case for this algro as its mostly flat to light rolling hills.
If a terrain block has any spike or other strong characteristic in it, then
the block won't drop a LOD or you will get popping.  This can be reduced by
geomorphing or making the terrain blocks smaller but smalller terrain blocks
puts more work on the CPU.  Also the stitching of the blocks must be a pain
and could generate thin triangles which tend to be bad for walking on.
  If your looking for an easy LOD scheme that you could code fast and the
terrain isn't that important then maybe this is the algo for you.  It mighty
also be a good place to start with terrain rendering.
