Josh has just published the tool he's been working on - CRACK.NET. Its a combo of Snoop and Mole and its pretty awesome. "Crack.NET allows you to “walk” the managed heap of another .NET application, inspect all kinds of values on objects, and even manipulate those objects via IronPython scripts"
You can read more about it from here

Thanks for the nice write-up! I just want to let you know that the links in your post to the downloads on my blog are all dead now. I've moved Crack.NET to CodePlex and the documentation file has a new URL, too. Sorry about that!
