As I mentioned in the post, this was for something in addition to newest nodes. I'm a great fan of it. However, because fo time, I often don't get a chance to go back to a root node I've read before to see if there is anything new. Thsi would be a help with it.

However, since there doesn't seem to be anyone else interested, I think I'm just going to try a Perl solution on my own and share it with PM if/when it becomes presentable.
