Hey Colin,
I've been using this:
def key_to_path(model):
key = model.key()
output = []
while key:
name = key.name()
if name is None:
output.append(key.id())
else:
output.append(name)
output.append(key.kind())
key = key.parent()
output.reverse()
return output

It is better to be wrong than to be vague.
