As long as they are up front about the commute requirements (once a week, once a month, once a quarter, whatever), that's fine. Employees can decide how far away they are willing to live.
I might be willing to do a 90 minute commute once a month, but not once a week. If once a quarter, then I'd even be willing to fly in at my own expense.
