This is not a viable updating mechanism as most nodes would cache the old version, and the insert path would probably be different to the previous one, and the new version would not propagate because the node returns the first version it finds. > > The second reason is more important.

This would be quite Yes, it can, however the mechanism to do this is to return DataReply rather than InsertReply, transferring the data from the original, which must validate correctly. This means that to attack an SSK, the node op must know the private key. > good at preventing people from uploading content and > it would require only a slight modification to fred. Suggest you make an attack for this, we'll test it and see whether it does any damage. > It seems more sane to have the node forward the insert > request along even if the data allready exists in the > datastore.
