I'd really like the pseudo-standard to be that if you're doing  
layers, the channel names should all be single-letters like Michael  
has there.  Are there cases where you reed to put more letters?  That  
would make it easier for people to make layers like "guy.head.spec.R"  
and you know that everything before is part of the layer name and the  
"R" is the channel.

And also, I think that is you have multiple channels that are tied  
together, they should always use the layer format, like Motion.X and  
Motion.Y.  I see some files that just say "X" or "Y" or "VX" or  
"velX" and there's no good algorithmic way to know they're tied  
together.
