Has anyone used or seen use of Nested Intervals (see  
[http://www.sigmod.org/sigmod/record/issues/0506/p47-article-tropashko.pdf](http://www.sigmod.org/sigmod/record/issues/0506/p47-article-tropashko.pdf))  
in Ruby on Rails? I need something like Nested Sets but also need  
something that can handle very frequent repositioning, adding and  
deleting. The problem with Nested Sets is they’re way to heavy for  
updates.

Just curious of any success stories or insight I can get on this.
