The company I work for does something similar. Everyone at the same level gets the same salary, with percentage variations based on geography. It completely removes the competitive and secretive nature I've seen elsewhere. And it also pushes each individual to live up to their title due to the extra transparency.
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.
