Despite the "Bah, Humbug!" tone of my previous mail, I am actually in 
favour too.  I just want to tease out the extent to which we would be 
giving developers what they say they want, rather than what they could 
actually use.

The value of JSON is surely that JSON support is widespread across a 
wide range of programming environments[1], rather than that JSON is a 
"simple" format.  Would the alternative formats being discussed offer as 
much, in terms of their practical implementation for a wide range of 
languages?

I was thinking of a dynamic web service, which would at least remove the 
latency issue.
