If there are protocol families that will be part of Java SE and 
supported in all implementations then they could be added 
StandardProtocolFamily. On the other hand, if this is platform or JDK 
implementation specific then implementing ProtocolFamily is the way to 
go (the enum extending interface pattern is something that we've used in 
other areas too).
