ABP just informed me today that 6 NUIG offers had gone out earlier in the month -- I'm assuming they're second-round, but I could be mistaken. They also mentioned that things are taking a while because 1) schools in Ireland have been on spring break recently and 2) many applications are being processed, including those not only from North America but also from Asia, Europe, etc. Finally, RCSI invitations for interviews have still not gone out, and interviews may take place from mid May to the beginning of June.
Finally, I was able to confirm that, in my case, my application was forwarded to all three schools to which I had applied, including NUIG.
