You can simply use multiple links to send same data. The fastest one wins, so if there's a temporary hickup on one of the links, you still get somewhat bounded

You can simply use multiple links to send same data. The fastest one wins, so if there's a temporary hickup on one of the links, you still get somewhat bounded latency. When things work fine, you get to reap the latency benefit. So I think it's plausible for intercontinental links.
