Ireland and England have something called the Common Travel Area (https://en.wikipedia.org/wiki/Common_Travel_Area) which is unrelated to the EU. Basically shouldn't be affected really. Only destabilizing thing that comes to mind would be the Scotland + N. Ireland leaving the UK might make them rethink this.

You are right.. I was thinking EU relating to visa requirements, but that is Schengen in much of the EU, including Ireland.
It seems there will be no change in regard to visas.
Will it still be possible to travel from Ireland to the UK without showing documents?
If not... then will there be a new fence across Ireland (between north and south)?
