I found recently a very interesting article about P2P networks and Skype. This comes as a completion of the other article
about Skype exposed posted here in June: Here is a permalink
It is written by some guys from Cornell and Google. Here is the article.
The most interesting thing is (copied included links):
“Garfinkel , concludes that Skype is related to KaZaA; both the companies were founded by the same individuals, there is an overlap of technical staff, and that much of the technology in Skype was originally developed for KaZaA. Network packet level analysis of KaZaA  and of Skype  support this claim by uncovering striking similarities in their connection setup, and their use of a “supernode”-based hierarchical peer-to-peer network.”
Heheh, I wonder what will happen if someone wants to exchange a file with multiple users, for example in a conference. 🙂
They close the article with this:
” Altogether, we find that Skype users appear to behave differently from file-sharing users as well as traditional telephone users.”
