Yes, but sponsoring the All Blacks makes you the sponsor of the country's biggest sport, and the biggest rugby team on the planet, and sponsoring Ireland gets you the third biggest sport and perhaps the sixth biggest rugby team on the planet (being generous). I'd be surprised if sponsorship revenues were that different.
As for Irish players abroad - there's rumours linking Irish players with moves over the water all the time. And not just the big name ones. Most stay put, although you could make a fair team out of Irish players who are/have been Exiles.
