Lasse,
for Java, you might even look at
http://docs.neo4j.org/chunked/snapshot/tutorials-java-embedded-traversal.html#_new_traversal_frameworkto
get some inspiration ...

Java.

Sure, it's like getting friends of friends:
https://github.com/maxdemarzi/neography/blob/master/examples/facebook.rb

This should work, but I haven't tested it, so keep an eye out for typos.

nodes = @neo.traverse(node1,  
  "nodes",
  {"order" => "breadth first",
   "uniqueness" => "node global",
   "relationships" => [{"type"=> "friends",
"direction" => "out"},
   {"type"=> "likes",
"direction" => "out"}],
"return filter" => {
"language" => "javascript",
"body" => "position.length() ==
2 && position.lastRelationship() == 'likes';"},
   "depth" => 2})
