I've heard from a reliable source that there was a public dialogue on A Generous Orthodoxy at Regent College a few weeks ago [mentioned by Mike Todd here], featuring three theologians (including Stan Grenz, who died a few days later...). The dialogue is now available via their bookstore. It's not all positive by any means.
The CD's name is: Generous Orthodoxy - a Discussion, product number: RGCD3438C. It's not yet listed in their online bookstore, but it can be ordered by calling Toll-Free (US & Canada) 1-800-334-3279. $12.00 (CDN) for the double CD set.
