There are a couple of things to do this already.
I also wrote arxiv-checker (since gone.). I'm not sure if any of these is perfect, though. arxiv-checker is limited in only checking arxiv, and also in the number of people and at the moment only does a month back in time. google scholar occasionally gets it wrong (i get sent alerts when the author didn't actually publish the paper), and scirate requires you see the paper pop up.
