Is some of this not the same as the solution to the Swiss issue? Which was IIRC solved by forcing Swiss jobs to be advertised only in Switzerland for a period, before they could be advertised elsewhere? Anyone could apply for them, but the chances of someone not in Switzerland finding the advert was seen as being low.
It sounds like this may be what's being advocated.
