Just adding a data point, mobile networks generally don't use dhcp so that limits the scope of dhcp as an option.

I anticipate mobile networks will need TURN.

we had discussed similar problem to discover PCP servers in Mobile Networks (http://tools.ietf.org/html/draft-chen-pcp-mobile-deployment-04#section-4) sometime back. Based on the discussion
1)DHCPv6 stateless configuration information is supported by 3GPP specification (http://tools.ietf.org/html/rfc6459#section-5.2)

2)Since DHCPv4 is not widely used, possible solutions discussed to solve the problem are anycast, enhancing PCO to provide TURN {PCP} server IP address
