Hate to spoil the really nice idea, which I really like.But to my knowledge, the molds are done(99% at least), which means any engraving would be actually an addition to the mold material (kind of mirrored in 3D).
Only Idea I could actually think of would be to mil something into an area, which would allow raised parts of the case (like besides the LCD). But even that might be a quite expensive modification to the mold, since it would mean to make the sparc erroding counterpart to build anew.
I think personally laser engrave something in your local hackerspace might be the more fitting option here. I like Binkys design, though.
