The Steam Workshop for FaceRig is now launched :)

Confirmed, together with mobile and a lot of other platforms, but only AFTER the windows version, and it is one platform at a time. The time-frame for each platform should be measured in months, but likely will be at least 5 months away, but probably more.

First up are the characters for Halloween and for some of the IGG backers who donated a lot. After that will be other characters either by own choice or chosen by the community in a poll.

Two options:

• The copyright holder allows: they are made / distributed by Holotech, when they think the time is right. If you directly know a copyright holder of a large game / character, you can of course ask them, and they can then get in touch with Holotech Studio's for more info. If you don't, don't spam their forums or so, since it is only likely that the owner will not give permission, and then Holotech can't make it.
  
• The copyright holder doesn't allow / doesn't respond: Holotech can't make the rig, but most likely the community still can if they do it for free. These rigs are then not distributed by Holotech, but by the community themselves either on the future workshop, or on http://facerig.us (which is the community made/managed site for FaceRig, not to be confused with facerig.com)
  If the copyright holder then asks for a model to be removed, it will be done, so know that models can disappear without notice.

For now, no, the reason being the following:
FaceRig uses tracking software by Visage Technologies. That software does not have built in body-tracking, so it would have to be build from scratch. If the Kinect is used for that, it would restrict the amount of compatible camera's, which is what Holotech does NOT want.
What is an option however is movements tied to keyboard shortcuts, but those too will only be added in a later stage of the program.

This is possible and is already done.
The first prop made were bunny ears (scroll down too) and the first avatar was Steve from Minecraft.
