Whatever you do, add ventilation and if you think you have added enough, add some more. If you do not believe me, go and visit some of Tokyos capsule hotels close to the party districts. Nothing is more worse than the feeling to breath what has very recently left intoxicated people from one or the other side. Also for the sake of avoiding drama on those trains, add snoring tests.

As a startup, there are two perspectives on these kinds of issues: just get something built and running as quickly as possible, or make sure you work out the kinks.

So far we've been very much doing the second. Built it, experiment on it, test it, make sure it works. Only publish what's actually feasible. Set up more projects to make sure all the kinks will be worked out. Work together with experts to ensure proper ventilation, noise and vibration control, etc. etc.

But as a startup, this process can be frustratingly slow. I am concerned investors may want to see quick results, not perfected solutions.
