Making a Lion portable install AFTER installing it

[lorax3]

Anyone have any ideas for making a USB/DVD copy of Lion after using the original install dmg to install it on a single system?

After the install the dmg disappears, and even if I wanted to re-clone my current machine I see no way of doing it.

I am unable to re-download lion (not even a paid option) as the Mac App Store already detects this machine has Lion on it.

Only (legit) alternative I see is to use another mac and pay for lion once again, and make a image before its installed.

Anyone else have any thoughts?

Eh, just saw another thread about option clicking the "buy" button in the mac app store.

Does not seem to work with a mac already on 10.7, but assume it will if I log in to a mac on SL.
