My two cents worth:
Aren't we missing something?  If we do away with the camshaft, why not 
do away with the valves as we know them?  How about an Iris?  Or maybe
some sort of sliding/rotating window?  Would seem to do away with the
problems of valve inertia when changing direction 180 degrees (up/down).
 And would reduce the problems with overcoming cylinder pressures?  And
then we could change port shape to something more useful.  Like maybe
a crescent moon shape instead of round?  Or many little triangles over
the whole cylinder diameter, with alternate triangles being intake and
exhaust?
Or maybe just one huge port in the head used by both intake and exhaust,
with redirection of intake and exhaust being done OUTSIDE of the 
combustion chamber?
Just a few off-the-wall thoughts.  If we're going to re-think things,
and using the old valve configuration doesn't seem to work, then let's
throw out the valves, too!
