We actually use this solution. But there is one caveat: if you have got more 
than 2000 nodes that reference the _same_ category you should use STRING instead 
of REFERENCE properties to store the reference. This sounds bad on the first 
sight because you loose referential integrity but with Jackrabbits current 
implementation you will run into performance problems because the references are 
stored in the categories item state which makes adding new references a costly
