I feel that Edmon's report of the ICANN/GNSO point of view and the 
positions of James Seng are shared by most of the groups we relate 
with (Internet @large, open roots, ISO lobbies, Multilinc, MINC, 
Eurolinc, ISOC France, ccTLDs, etc.). If this WG does not think they 
are technically adequate there would certainly be a real urgency to 
document why, to have it confirmed by the IAB, and disseminated. This 
is due to the constraints a change would introduce outside of the 
Internet community and the général awareness of this debate after the 
Paris meeting. This WG needs to speak up now, or status quo will be 
considered as definitly settled.

I expect one single sign (logo) gcTLDs [geocultural] to be documented 
this year for multilingual information machines (airports, 
transports, health, kids, disabled). BTW this is also why I would 
recommend to refer to the semiotic rather than to the semantic aspects.
