Well, there is a real meaning between these grandma-mother-baby qualifiers, that
would be lost with a BL1, BL2, BL3 scheme. You need only one grandma-BL (Jarl
doesn't use the term, but in my mind it's the part responsible for "centralized
distribution") to control a whole "piper program". You need many mother-BL's
(one on each machine) for one grandma-BL. The same way, there are many baby-BL's
for one mother-BL (many baby-BL's on each machine). If you don't like baby and
grandma, what about super-BL (SBL), mother-BL (MBL) and child-BL (CBL)?

BTW Jarl, your document really reflects what we agreed on friday!
