One more question - is there a configuration option to disable this?  My 
application of batman-adv and alfred is not for a wide area network 
providing internet, but rather to setup a mesh between master nodes of 
my private network for data sharing and synchronization.  My private 
network at the moment has no plans to utilize IPv6 and we would like to 
keep it disabled if possible.

At the moment I am guessing it would be a code hack to switch this logic 
to use IPv4 instead?  Or am I over-analyzing this and really it isn't a 
big deal, I just need to get the right configuration setup?
