Kazaa/p2pnetworking ports

Howdy,
Whilst checking the access log on my router I ran across accesses to port 3531. A little googling leads to the discovery of 2 (4) ports not listed in nmap-services. Perhaps they could be inserted into the distributed nmap-services file for the next release as such:

kazaa             1214/tcp   # Kazaa File Sharing
kazaa             1214/udp   # Kazaa File Sharing
p2pnetworking     3531/tcp   # P2PNetworking/PeerEnabler protocol
p2pnetworking     3531/udp   # P2PNetworking/PeerEnabler protocol

3531 might be better named 'PeerEnabler', since that's the name of the product and P2PNetworking.exe is the name of the executable. Or the company name could be used, "Joltid".

On PC's where Kazaa has been installed and run, P2PNetworking.exe opens up port 3531, and it stays open even if Kazaa is closed (it is a separate process, and the port is not configurable). If it is not running when Kazaa is launched, it will be started- but never stopped. 1214 is open only when Kazaa is running, but 1214 is only the default port (user-configurable).

There's a short and sweet thread about this:
