Not low latency, but onion-adresses/services are actually ideal for this. You only need to know the onion adress, to know that you connect to the correct node.

* encrypted * automatic NAT punching * complete location independence * use 0MQ with tor as transport if you want a queue on top .

Or if it has to be fast and low latency: 0MQ with eliptic curve encryption.
