What is the minimum height of a full dimensional n-simplex whose
vertices are members {0, 1}**n ?

Equivalently, what is the minimum non-zero distance to the origin from
a hyperplane defined by members of {0, 1}**n ?

The answer is at most 1/sqrt(n) .
The corner simplex provides an example.

A smaller answer might be possible if the simplex is oblique enough
that the height-defining segment does not lie entirely within the
hypercube.

Anyone have the answer or a lower bound on it?
