I can use photoshop and skin with it easily but I would be interested to see the tutorial finished, also it might turn out to be helpful to people who are new to photoshop and skinning.
Only problem I see is if you can use photoshop you can skin using photoshop. Whereas if you can't use photoshop, you can't skin using photoshop. So it wouldn't neccesarily be a tutorial on skinning basics, more on photoshops basics.
