keynote talk by M.Abrash-Please help

My question relates to the keynote talk at Oculus connect.

I wish Michael would talk more about the ways in which the multi-focal point problem (at around 30mins) is being solved. He just said that there are a number of ways to overcome this with all of the solutions involving new hardware and significant changes to the rendering model. So what are these 'ways'? Everything hings on this lack of a multi-focal solution according to this talk.

I want to know how Oculus (or anyone outside Oculus) is working to solve this problem.

Thanks,
Kane Waterworth
