So you got an “older” (pre 2011) MacBook Air with read-only USB recovery thumb-drive (stick)? Well, turns out it is only read-only by some firmware lock bit. Just run:

sm32Xtest.exe

On your favorite Windows (virtual-) machine to toggle the read-only bit. You now can use it for your personal data, or writing the Lion installer disk image to it to gain a Lion Recovery USB key, just as you like.
