• Looks in registry (Host Cache) to determine Seed Supernodes
• Send UDP packets to specified HC IP addresses and ports
• Wait 5 seconds• Attempt TCP connection to
specified HC IP addresses and ports
• Attempt TCP connection to specified HC IP addresses over port 80
• Attempt TCP connection to specified HC IP addresses IP addresses over port 443
• If none of these work cycle through all of them 5 more times
• Assuming connection made, test local workstation to determine available bandwidth and available CPU
• If results are within specified (unpublished) parameters, report back to central servers that this machine is available to be a Supernode
• Start encrypting traffic

Applications: Barrier to EntrySome applications simply die because lack of end to end make it too difficult to work.
“The time has come to lower the curtain on Speak Freely. No further development or maintenance will be done, and no subsequent releases will be forthcoming. The Internet of the near future will be something never contemplated when Speak Freely was designed, inherently hostile to such peer-to-peer applications.”

Security: IPsec
IPv6 is no more secure than IPv4
IPv6 is no less secure than IPv4
IPv6 can be deployed in a more secure manner than IPv4

Security: Training
Security models will change
Security Architects/Engineers need v6 training
Training needs will be extensive for senior architects – allocate training funds

Peer to Peer isn’t evil
Peer to Peer ≠ Napster or Kazaa
These are just ‘early adopters’
Can be managed and leveraged in your organization
