Bear with me here, i'm used to thinking of such things in a windows, download .iso, burn to disk kind of way. I'm guessing somewhere on our hard drives after downloading Lion from the App Store there won't be a handy .iso anywhere. What if there is a .dmg though? Could that be made bootable somehow? What about a .pkg? (Sorry, not proficient enough to know this yet) Just thinking out loud here, and wondering whether it's possible for us to make our own DVD's on release? Anyone have any thoughts on how we get around this? How have developer previewers managed?
