"news publishers get a right to ask for money from snippets scraped by aggregators and search engines like Google"
Solution for problem that does not exist
If a news company does not want a snippet of their story indexing - robots.txt can stop search engines. And if robots.txt is ignored then legal avenues to take.
Don't expect a search engine to pay to index your content they do not want to give away profits needlessly
.. and then the fine line between news company & citizen journalist - your average (wo)man on the street might fond a juicy news exclusvbe and publish it online. There's plenty of newsworthy dirt dished up on dodgy council behaviour by disgruntled council tax payers (as an example of stuff the big news companies do not bother with as regional journalism cut to the bone but happy to print later)
Given that plenty of reports saying many people are incraesingly getting their new from social media, will "News companies" start getting cash from people posting on Twitter, Facebvook, whatever?
Maybe I'm odd, but hardly ever use search engine to find news, get news from visits to a few sites I regulaly visit, some news co specific apps and news email / RSS subscriptions..
Only time I do use search engine is to discover the news that someone is trying to hide in the UK via a super injunction
