It was proven to work efficiently in LAN networks where multicast DNS is used. In the WAN environment where for the proper registration and discovery a control over regular DNS servers is required the solution approach a barrier.

As one of the possible ways to overcome this obstacle was introduction of bridging solutions. The problem with this approach is scalability.
