Just noticed this and i'm quite tempted by it. If you go here its got instructions on how to get the NXE now.
The only thing you can't do is go on xbox live but i think i can live without that till the 19th. My only fear is, that my xbox will get bricked but i can't see microsoft doing that as i could have just put my friends hdd on who has NXE 'accidently'.
What do you reckon. Is it worth the risk?
