Fwd: Wanted : Solid/documented/tests Nested Set Model class for mySQL.

Hi. I'm looking for a class that implements nested sets, ideally using ZF (1 or 2) or PEAR, or, if standalone, clear enough documentation. My data is essentially social referrals and will be nested very deep, so this would seem to be a perfect match for this sort of store, but I'm being a little lazy and looking for a good recommendation. I've done searches on google, et al, but looking for recommendations from real use, rather than "this looks good".
