The way auto rig works:
You first create the biped guide, this is what you move and resize to fit the model. when its all sized ok, it creates the rig (with controls) from the guide (you can then deleate the guide) and then you skin it onto the model (called envoloping in XSI)
as its a normal bones rig thats created, you can add or take bits off it just like any other bone system.
there is also a quadruped guide and rig that works the same way.
I ment that it is generally an arse to learn, it probably has the second steapest learning curve i have encountered (after blender).
Some people think XSI has the best animation tools in the game, I am still undecided (having come from maya and not got too used to these ones yet). But it all seems fairly decent and good. As I said before, XSI is much more production proven for games, and are certainly going after the games market (and sucseeding). I hear most japanese games, tv and effects studios use it (capcom noteably in resident evil 4), valve used it for half life 2 and I think its being used in the next Unreal game.
It has alot of useful game tools that you don't see anywhere else and is fiarly easy to script in too add your own tools.
Also I hear it takes quite along time for messiah updates to come out (these are all off forums, but you know how unreliable they can be :) ).
