[Tagging] direction=forward/backward on nodes ?

I'm surprised that so many people are jumping to this conclusion. Let's 
remember that a way is just a series of nodes in a particular order. So 
a node is not necessarily an isolated object. In many cases, it exists 
solely as part of a way. Thus the concept of direction is not 
meaningless for a node which is part of a way. I haven't examined any 
uses of the tag on a node, but I can imagine, for instance, that a node 
in a way with a direction attribute might be used to represent a 
road-sign that applies only to traffic on the way passing that node in a 
particular direction.
