Some friends of mine (first degree friends, this is verified) moved to Dublin and just, well, didn't leave. At least in 2006 it was rather easy to get a tax identification number (I forget what it's called) with a signed affidavit and a witness saying you live at some address, and you can use that to get work. Now, without better documentation the government taxes you at the highest rate possible, and since you won't file you'll never get a penny back. Also, they worked in card houses, so maybe the documentation requirements weren't as strict as a professional programming environment. Oh, and I'm sure it's all sorts of illegal. But just doing it is easier than it seems. :)
