Fairly simple.
When you download from the App Store, BUT BEFORE you install, you use Disk Utility to make a dmg file. You burn that file to DVD or put it on an external drive. You now have your dmg installer for backup.
Then you install Lion on up to 5 Macs.
I fully expect that Lion will be installable on a bare drive (like SL is) as well as an upgrade over SL.
