In my company, DR means a disaster has struck, e.g. a building has been 
destroyed. So, you typically don't:
1)Do a DR failover for any trivial reason
2)Do a DR failover automatically

So, just run a normal replica in the DR, and have a config file ready to be 
able to "promote" it to a master. If you need slaves there too, just have 
them replicate of the "DR master", so you have less config changes to do in 
the case of a real disaster.
