Character Controller latching onto a moving object

Hi,

I'm working on a first person game in Unity which employs the following mechanics:

*First Person Perspective

*Zero Gravity

*Physics Collisions between the player and freely moving objects in open space

*Pushing off of said free moving objects, and having appropriate zero gravity physics reactions

*Attaching to objects with the player character, then moving along the object's surface while latched on.

*Camera mechanics so if you keep moving your view up or down, there is no stop point, it is looping.

I'm having trouble implementing the last two, and I was wondering if anyone could offer any help. I am coding in C#

Thanks!
