Subject Re: Replica data distributing between racks

Jonathan, 
	I think you are saying each DC should have it's own (logical) token ring. Which makes sense
as the only way to balance the load in each dc. I think most people assume (including me)
there was a single token ring for the entire cluster. 

	But currently two endpoints cannot have the same token regardless of the DC they are in.
Or should people just bump the tokens in extra DC's to avoid the collision?  

Cheers
Aaron
