the current implemenation does no grouping of signals.

maybe you already know this, but it's not enough to  just insert a node at the 
right position - it needs to be part of the way.
it's possible that you can insert several nodes (as part of a way) on the same 
coordinate, although that would lead to segment with length zero. you will have 
to see if that breaks something.
