Hey Viv,
I just happened upon this today:
http://compositewpf.codeplex.com/ Just a few minutes ago actually, so I haven't really delved into it. I don't know whether or not it contains additional stuff that you haven't already run into, but I just thought I'd throw it out there for you in case you hadn't already run into it.
