I just discovered another discussion of JANT, by Walter Russell Mead - Faith Matters Sunday: The Jewish Discovery of Jesus. He doesn't, however, review it, because he hasn't gotten it yet from Amazon. I'll be curious to hear what he thinks of it once he has a chance to read the commentaries and essays.
And here's some more:
From the JPS Blog - Rachel Broder discusses the book.
Joe Winkler on Jewcy again mentions the book, but hasn't read it yet.
A discussion on Project Quinn by Jessica Youseffi.
A very nice review of the book at Ancient Hebrew Poetry (John Hobbins).
