[UCR] Use case for Betfair?

Ooops! Again, with the topic, this time...
---------

Hi Alex,

Thanx for joining the WG, and welcome.

I wonder: what is Betfair use case for rule interchange? I am mostly 
curious, but, also, I wonder whether it is covered by one of the use 
cases in the UCR WD [1] or not?
