I will be interested to hear your perspective on it. I personally would have used the word 'constructed' rather than 'invented', but I tend to have a somewhat different take to Ehrman on this kind of issue. :-)
I am eagerly waiting a review of this material from you, and your colleagues on here. Honestly, if you all (the Jesus Blog Crew) would be willing to take a request it would be awesome if there was a chapter by chapter review of the book. Anyhow, looking forward to whatever comments will come.
