Who Sits Next to Jesus?

 In reading Mark 10:35-45 today, I began to wonder, and, frankly, speculate about who really is sitting at Jesus' right hand.  In that story, the brothers James and John asked Jesus if they could sit at his right hand.  What they wanted, of course, was earthly power because they thought Jesus was going to establish an earthly kingdom. Jesus doesn't tell them that they are wrong about the kingdom, but that they are wrong about the role of power.
  However, I got off on speculating about who sits with Jesus.  My first thought was that it might be Mary and Joseph, two important people in Jesus' life.  Then I thought about the Transfiguration and reasoned that maybe it was Moses or Elijah. I even considered Judas as an example of what a forgiving Father God is.  In the text, though, Jesus seems to imply that whoever it is will be someone who is a martyr.  Perhaps Peter?
  Could it be a rotating position with all the saints getting a turn?  I don't know.  Who would you nominate for sitting next to Jesus?
