Yeah, that could probably work for text as well

That's the unicast configuration setting. At present, it's just a binary setting (called 'prefer unicast'), which will enable the sending of unicast hellos, and switch to using the unicast hello history to compute the cost to any peer that sends them.

I'm planning to expand the option to also support disabling multicast entirely, and to support specifying unicast peers in the configuration file. I have also yet to add support for sending other TLVs as unicast.

Yeah, haven't gotten to that part yet...
