For the threaded discussion demo I did, I saved all the parent  
document ids in the child document. If you create a view indexed on  
the parent list (and a timestamp) you get a nice threaded threaded  
list of documents. Finally with a bit of startkey= and enkey=  
trickery, you can limit it down to "one parent and all its children".

This is obviously not very friendly towards changes to the tree  
structure where you move nodes and/or subtrees, but that is still
