Ok, I'm not 100% sure on this; this is what I've pieced together... I'm sure you'll still be able to do the plain old manual installs. Why do I say this? Simple, if the only way to add stuff to P5 where through paradise, then everyone who's ever bought anything from DAZ would have to re-download the re-packed item (definitely an expense to DAZ, bandwidth/re-packing). My guess is, this is just an easier way of installation, but not mandatory (At least I hope so...) But anyways, an answer from Curious Labs would be nice on this one...
