I'm not sure what the preferred way would be in D6, but in D5 and 4.7, this could be set by content type via Node Family (http://drupal.org/project/nodefamily)
I've considered use cases for singleton type nodes in the past as well. It would be relatively straightforward to implement, so there is probably something existing and more current out there in the contrib space.
Ah, here's another one, but again it doesn't seem to be D6 ready: http://drupal.org/project/node_limitnumber
And .. aha .. here's one for D6, found a reference to this one in the previous one's issue queue :) http://drupal.org/project/node_limit
