Opera is a great browser. Not perfect but it's one of the winners. People who think otherwise should maybe check out the current version ; }
But Opera the company isn't the puny thang it was a bunch of years ago. They aren't just going to hand over the codebase to some community and hope something gets done. They've already seen where that leads.
So it comes down to PAYING Opera to port to a platform. QNX did that a few years ago, when it looked cheaper and strategically smarter than spending man-years bringing their own browser up to current standards - or getting Mozilla working well.
Genesi has looked into Opera too. It's been discussed with Opera, and the cost is not trivial. It's not an amount of money a company in the Amiga community will willingly part with if it means only putting it on a few thousand machines - at best! - and not even owning the IP.
It begins to make sense if the amount of machines is a lot higher because of bulk sales into other markets entirely (or if several companies can come to terms with splitting the cost and having it ported to a commonly agreed set of standards and APIs).
