Look Britain, check it out.

Wise up. There'll be a United Ireland when we VOTE for it.

I personally get the feeling the British Parliament can't be bothered with us anymore, however you Irish don't have some of the benefits that the British do.

Also I want to give Northern Ireland just being a separate country a go because the Northern Irish seem to be very proud of being Northern Irish. :P

You might think I'm out of place here, since I'm from Eastern Europe, but I'll write down my opinion. Sometimes a third party review seems like the best thing. :D
There might be many reasons back in history for which the english would want to keep Northern Ireland for themselves, but do they need it now? We're living in the 21st century after all.
I'm not sure though how much independent are the nortern irish, and to what extent the british have control over things out there. But i do rezlize it's an extremely complicated conflict, but i can imagine it, since my people have been through the same.
The British Empire is no more, and if there are so many irish living in England/UK, then they shoud raise their voices for finding a solution on this problem.
The main thing, which should be heared in this conflict is whether the nortern irish want to join Eire... because I know, that most of the people there are catholics, and there are plenty of prods in the north. So in a way, the nortern irish are different people, maybe they would fear being discriminated or something.
My country (Bulgaria) was separated by a number of treaties in the past also, and the people from Macedonia, who were our brothers just a century ago were brainwashed by the serbs and now they hate us. xD Those macedonians are very interesting people btw. :D They speak bulgarian dialect, but they hate us, they are not civilized people with historical knowledge and you can't conversate withem in a civilize way, cuz they were thought and raised with lies for 50-100 years.
You don't want that to happen in Northern Ireland, and that's why you should try to solve this problem right NOW, in the 21st century, before the nortern irish have decided that they should have a separate country from Eire. Now that IRA is disarmed this might be very likely to happen in 50 or more years...

I write this because i'm very sympathetic to the irish people, also the basque people, catalonians and other opressed peoples. My people were opressed for 700 years (200 years by the byzantine empire, 500 years by the turkish Empire and 50 years by the soviet empire), and we gained our freedom at a very high cost, having been ruled by the communists for more than 50 years, just because the empires decided to separate our country and leave us to the commies. Before that the english and the french supported the ottoman empire, closing their eyes and ears to the savages and the outrage done by the latter.
I'm sick of empires, and every nation who decides that they are the greatest and start acting and policing the world like such... Guess who i meant. :D
