Derek,

Even with the enormous amounts of data that Google is handling there
would be no problem at all creating an algorithm that has virtually no
chance of collisions. An 128bit UUID can have 18446744073709551616
unique IDs for every single millisecond. You can read about UUIDs here:
http://www.ietf.org/rfc/rfc4122.txt

Java even has a class for this from 1.5+:
http://java.sun.com/j2se/1.5.0/docs/api/java/util/UUID.html

Lets move it back to theoretical.. ;)

Cheers,
Mikael
