I am intimately familiar with mpkg/mdmg -- I provide an all-in-one 
installer for Myth[1].  For that, I use Parallels to maintain an 
isolated prefix for building (and others for testing.  It occurred to 
me that the existing infrastructure of MacPorts provides _most_ of 
what would be needed for delivering pre-built packages to 
less-sophisticated users.
