When you purchase Lion from the Mac App Store, you can install it on all your authorized Mac computers. Just sign in to the Mac App Store from each Mac and download Lion from the Purchases list.
So, if you are able to D/L Lion from the AppleStore on the other Mac, then you can use the installer you created (just saves you the d/l time), however, if the other Mac uses a different Applestore ID then you should purchase Lion.

1. Given long download time, can second system be upgraded from a DVD without a second download?
2. I plan to do a clone of both drives before the install, in order to protect everything. Can they both be cloned to the same drive? (I thought I would just buy a new drive for this)

I used my bootable install disk on a USB HD to install Lion on my wife's Macbook (saved from when I upgraded my iMac). I downloaded nothing. All went well. I guess I must have authorized her Macbook using the same credentials as mine (bought them at same time 3 years ago). I used her Apple ID to set up iCloud. Everything seems to be working.
