Interesting animation features (put in Blender?)

I got the link to this page at CGtalk, I watched the video and there are some intersting animation tools he uses (I think the prog was Maya), I just thought I might bring it to the attention of the powers that be incase they need ideas on upgrading Blender’s animation tools.

I am pretty sure that developers are fully aware of Maya, XSI, LW, etc. capabilities in this area.

HOS and others will be making changes to the anim tools, you can count on that.
