(a) I can't see how this will work without recreating all the problems
of the dense-minor schemes in slightly different dress and (b) it
limits you to a max of 63 partitions per drive.  (The latter seems like
infinity now, perhaps, but with drives pushing 100GB, I'm not at all
sure it'll stay that way.)

Oh.  Okay, I think we're talking about different things.

By "recursive partitioning" I mean that any partition can itself be

That's "any partition".  Not "any MBR partition".

The most immediate need for this is dealing with MBRs.  But installing
a solution that addresses only that need strikes me as extremely
