We at JSK, has similar situation as vigar, we had a lot of (un-organized) ROS-Software also used in DRC and has been applied to several robots including open and closed robot.

In my opinion, a Humanoids SIG is a very nice idea, as still many software/approaches are not that easy to reuse for different humanoid robots as they probably could.
I agree, and teams like us, it is not easy to switch from existing system to others, but projet like
- re-create humanoid msgs and rep http://wiki.ros.org/humanoid_msgs, http://www.ros.org/reps/rep-0120.html
- create visualizer (rviz plugin) for these msgs
- From our experience of moveit applied to humanoid robot, https://groups.google.com/forum/#!topic/moveit-users/SP9kH4Ck0yY, we need IK interface for trees (improve kdl_kinematics?), add interface for calculate COM, Momentum and others (kdl_kinematics? robot_model? ), balance calculation method? these could be basics for all of software
- need mathematical library for humanoid calculation, Preview Control, Resolved Momentum Control? Riccati Equation, …
