I believe you may be wrong there black sheep, my understanding is that a person would have needed to satisfy the conditions for unemployment benefit(in terms of contributions paid) based on 2007 this year and 2008 next year. Therefore the person would only qualify for JA and even then it would be based on a habitual residency condition.
You are right in saying, however, that his best bet would be to transfer his benefit from the uk BUT this will only last for 78days.
