Anyone been watching Lilyhammer (think it was on in the US last year, but it's on BBC4 in the UK at the moment) - it's a sopranos-esque spin off (although not officially anything to do with the sopranos) that features a charactor very much like silvio going into witness protection and being relocated to Lillehammer in norway.
It's a little slow at times, but actually pretty good. Definitely worth giving a go if you liked the sopranos!
