Well, I don't think it's particularly easy. Generating the filters 
isn't the hard part, but getting them inside routers has always been 
quite a challenge. But that should be better than it used to be now.

By the way, you don't mention filtering based on routing registry 
information in your book. (I do mention it in mine but don't explain 
how to do it as I have never done it myself.)
