well, I know allot of noobs (including myself) at first have problems creating custom marking menus, and setting up custom Hot keys. This would make a nice little Vid.
Also, perhaps some form of guide to Maya Nodes. The Hypershade is full of Nodes that allot of people have no idea how to use. That would probably go down well.
Perhaps I vid that guided you through setting up a psd network, and also setting up Nodes for texturing. Allot of people seem to have problems with texturing and projections.
The transfer Attributes sounds like a nice idea. Show people how to Transfer surface detail from a Hi-res model to a Low. This will be a great help the growing number people interest in Next Gen Game content creation.
