Mobile alcohollock

About a year and a half ago I asked if there were any chance that some company could come up with an alcohollock for the mobilephone and I'm still on a look out for one.

That will save me alot of explaining to friensd and others the days after a big party. As you know what seems like a great idea at 3 am after/during a huge night out with your friend alcohol is NEVER a good idea in the morning of the soberness.

I*m for being able to set the promille halt where it will go "SORRY you are to drunk, sober up and try again" and ofcourse 112 will always work no matter what state you are in!

With writing sms it would be good to get a question "are you sure this is appropriate to send while your are in this drunk?!"
