CORS and Uniform Messaging People,

We are now just a few weeks away from the February 2006 start of what  
has now become the CORS spec. In those four years, the model has been  
significantly improved, Microsoft deployed XDR, we now have the  
Uniform Messaging counter-proposal. Meanwhile, the industry doesn't  
have an agreed standard to address the important use cases.

Although we are following the Darwinian model of competing specs with  
Web SQL Database and Indexed Database API, I believe I'm not alone in  
thinking competing specs in the CORS and UM space is not desirable  
and perhaps even harmful.

Ideally, the group would agree on a single model and this could be  
achieved by converging CORS + UM, abandoning one model in deference  
to the other, etc.

Can we all rally behind a single model?
