I suppose that deterministic keys generation feature will be ready for testing a few days later.

Some examples using incredibly experimental snapshot:

Root address 4F53LwSnLvWCj6AiDsipYR9rSvwQCmE4be (random key, created by OpenSSL):

validateaddress 4F53LwSnLvWCj6AiDsipYR9rSvwQCmE4be
{     "isvalid" : true,
     "address" : "4F53LwSnLvWCj6AiDsipYR9rSvwQCmE4be",
     "ismine" : true,
     "isscript" : false,
     "pubkey" : "020f253f0518bed2e7ca9faaaa13505fea6ed5f119dfca82c2aa6d6a05f69608d9",
     "iscompressed" : true,
     "nodemeta" : {
          "parent" : null,
          "depth" : 0,
          "sequence" : 0,
          "code" : "12d636d06b3f0b5f16c055e327b8eb1979968e8c9d76fbeec9db893952bbcdd1",
          "method" : 0,
          "generator" : "random"
     }
}

Root childrens (depth=1 nodes, created by private derivation function):

validateaddress 4Pe8Ma3xWsoNH3dv2UQgxREkpGuZVotNhM
