Avoiding a so-called "hard border" on the island of Ireland that many fear could disrupt the peace in Northern Ireland is the last major hurdle before Brexit talks can move to negotiations on Britain's future trade relationship with the EU. The other European Union state members are backing Ireland on this.
Under the plan the Northern Ireland Executive would be given sweeping authority to keep laws in the province close to the European Union single market rules.
If you must go, they said, then leave the inner Irish border open and put your customs and immigration controls between Northern Ireland and the rest of the United Kingdom (which are conveniently separated by the Irish Sea).
The role of both Irish nationalist and pro-British unionist parties from Northern Ireland in the Brexit talks has been hampered by their failure to restore the province's devolved power-sharing government since its collapse nearly a year ago.
Lost? Does she think we had a vote in Brexit?
European Union officials and diplomats have in recent weeks been scoping out terms for a transition and various kinds of free trade agreements - work meant to speed up the start of talks on those issues in anticipation of agreement to open the second phase of Brexit negotiations at the December summit.
The negotiations had descended into a war of words this month after an internal EU paper suggested that it was essential for Northern Ireland to remain in the single market and the customs union to avoid a hard border.
However unionists and government ministers have strongly resisted the idea that there should be any checks on trade between Northern Ireland and Great Britain - claiming this would disrupt the UK's own home market.
The Daily Telegraph reported that London and Brussels have now accepted the British will pay between €45 billion (Dh2221.3bn) and €55bn, with the final figure depending "on how each side calculates the output from an agreed methodology".
"We can't even draw the border, we don't learn this kind of thing". They could dream that with all the coming and going across an open border, the two parts of Ireland would grow closer and eventually reunite.
The UK government will find this hard to sell to the DUP, on whom it relies to stay in power.
According to one lady, this is where the Irish border is.
So far, so bad - Dublin won't back a new stage of Brexit talks until Britain comes up with something more solid than vague assurances and a patronising "calm down dear, it's only a negotiation" attitude, which has done nothing but pour oil on the troubled Irish Sea.
That included areas like agriculture.
