I am not sure what deal is between RTE and FAI, but from this press release in 2007, the current deal is up sometime this year.

Their Sky Sports contract also ends in this year.

So, why not include a LOI rights package along with the Ireland internationals, possibly with Sky Sports. Like, they have to show LOI games if they want Ireland matches, I don't see an issue in doing this, cause Sky Sports are likely to renew the deal due to high number of Irish subscribers they have in Ireland and the high numbers of Irish living in the UK, plus if Irish people see that games are on Sky Sports, they might take the league more seriously as Sky Sports are covering them.
