I imagine most hand makers will be working on, or already have completed, Bento enabled versions of their hands. Hopefully they send free updates but probably not
DamienFate: Yes. On my other plurk about it, also question was asked about being able to pose other people's hands. (like a photographer will pose a client with their hud)
Yeah I can add a puppet function. Though currently knee deep in a lot of production pre-xmas so I might not be able to add until the new year. I'll try though!
