For case 2b and 2c, I think Tab's ideas now work by adding the  
animation to what I call the "unadorned" selector (i.e. the foo  
selector in your example).  I believe you would want the "play-in"  
concept so it plays when it transitions to that state but does not  
play when the page is first drawn.
