Haven't read that one, was goign by what was stated in Mechanicum (where, Psi, the Noospheric technology described as allowing properly equipped techpriests to communicate on that intimate level).
Presumably, however, Zeth's Noosphere technology was lost with her if later generations of 'noospherically enabled' techpriests are vulnerable.
