I work for a large (30K employees) company that does something similar. For each job title, there is a salary and bonus range. So from someone's title in Outlook, you can pretty much guess their salary within 10% or so. This information is all readily available to all employees, though I don't think it is shared externally.

I work for a large company that does this - except it's pretty much useless for guessing someone's salary, because the salary range for each job title are something like $X to $2.25X.
