And, indeed, the virtuoso percussionist Dame Evelyn Glennie, who is
profoundly deaf, reputedly 'hears' through her feet. Given how
delicately she can play (she performs barefoot), she must have
exceptional sensitivity in her feet. She claims to have trained herself
to hear with other parts of her body than her ears
(http://www.evelyn.co.uk/Resources/Essays/Hearing%20Essay.pdf).

Most systems that try to deliver sound directly to the ears

That's not necessarily true in theory, but certainly is in practice :-)
The ability to move our two acoustic sensors leads to capablities
that are often ignored when describing the way some system is
supposed to work (or not work). For example front/back resolution
(which is not disputed), but in theory also resolving phase
ambiguities well above the usual 700 Hz or so limit, identifying
reflections as such, etc.
The other thing that is widely ignored is that our ears are not the
only way we perceive sound - I'm sure (well, at least I hope) Eric
will confirm that even profoundly deaf people can perceive
(particularly low bass) sounds through their direct effects on our
bodies, which simply aren't stimulated at all by headphone
presentations.
