Stupid question perhaps Robert, but could you not say live in Eire - must be plenty of nice villages near the border, some friends of mine live in Muff and say it's beautiful, BUT continue to commute to work in Belfast.
Then, you're living in the republic, but keep your job where it is.
Actually, just looking on Google Maps, it looks an awful long distance, same as me working in say Liverpool. Maybe it IS a stupid question.
Was just trying to throw ideas at you to see if any could be of help
