while the above may be true, it's competely irrelevant to the question 
at hand. there is zero chance that existing apps would work properly
with IDNs even if UTF-8 were chosen as the representation.  all apps
will have to be modified (many will require significant modification) 
if they want to deal meaningfully with IDNs.

conversion between ACE and UTF-8 is trivial, and the code to do so will 
almost certainly be produced as part of this group's effort (regardless
of which ACE is selected).  lack of vendor support for ACE is therefore
not an issue.

it's good that more OSes are supporing UNICODE and UTF-8, and this will 
make it easier to implement IDNs on those platforms.  but it's not enough
by itself.  we still need ACE, and we still need nameprep.
