Thanks for the hint. I don't want to use CoolUri for enforcing 
uniqueness, but for displaying the unique titles, and for this it is - 
who would know better than you - perfectly suited.
And alas, no, I cannot set a UNIQUE index on the page title field since 
the database stores deleted records, too. I could not even set a unique 
index on (title, deleted) because then it would become impossible to 
delete a page if another page with the same name is already deleted.
And my editors would deem it mighty unprofessional to be confronted with 
MySQL error messages which they should never see in the first place. 
This would be nearly as bad as the silent input tweaking which Typo3 
does with not-unique values in the alias field.
So I assume I'll have to write my own extension for that.
