Okay, now I understand that your last emails weren't just full of nonsense, but we have a very different idea about what is saved in the nodes. (To be honest, I think I didnt read the message where you proposed the 6-tuples carefully, so it may be my fault). I'll try to make some sense out of your email and come back to you. If one cannot fake those messages you're taking about, we still have to compare the extra overhead in the nodes with "just save the damn hash everything else is implicit". until later :) Kosta Yahoo!
