One significant obstacle to a maglev building elevator would be the safety
issues solved by the Otis elevator brake. Perhaps it's not such a stretch
to solve the issue, but then is it really a maglev elevator?

I do think you've got a really good point here, and I suspect the issue
probably revolves around the expense of building such a beastie. Have you
done a cost analysis Henrique?
