Yes, I have...
But that requires that you save the "Install Mac OS X Lion.app" file before actually installing it on the first machine. The install process deletes the install app when it finishes.
You should have not problem downloading it again fro MAS on a second machine. If you then save the install app you can use it on a third machine without a download.
Or if you by chance had a backup run before the instlal started you might have captured a copy of the installer.
Unfortunately, this is the way Apple chose to implement the new install procedure.
