Alice and Bob

The names Alice and Bob are often used in explaining communications processes and crytopgraphty. The recent example I encounter "Alice" and "Bob" is reading technical documents about the call set up of SIP VoIP phones. Instead of saying "Person A wants to send a message to person B", people rather use "Alice wants to send a message to Bob". This makes writing, explanation and presentation easier to follow.

Apart from matching alphabetical order, the two names also have already represented both genders, male and female. Wooo.... funny indeed ...
