ObservableSetTreeContentProvider is in CVS somewhere, if you check out 
the databinding sources you should find it.

I've written my own ObservableListTreeContentProvider, which I'm 
contributing to JDB, however it is not well-tested at the moment.  The 
patch is in bugzilla 207858:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=207858

A known problem is that if equivalent nodes are present at multiple 
points in the tree and one of them is removed, the content provider 
loses track of the other equivalent nodes.  Not a big deal if you're 
just using the tree in view-only mode though.
