Re: Norway is in EFTA and Schengen...
Exactly. Although it's interesting to hear about the Norway/Sweden system, it's not going to be any use on a border that *has* to be 100% "hard". In May's version of the future there can be no more free movement of people between the UK and the EU (and therefore Ireland), so everyone crossing will need to be stopped and their documents checked. The only reason the government isn't coming out and admitting this is that they want to kick the can as far down the road as possible in the hope that some act of god turns it into someone else's problem.
