Hello Cory,
I just sent a message over to Jim Austin, Editor of NextWave, because I too could not find a dedicated section to Application Scientists. However, you may try searching there for Technical Services careers, because this is another way that those jobs are often referred to.
Here's an article that I wrote on Science's Next Wave which is about several non-bench science careers, and we've incorporated a number of links into it so that you can refer to other pieces as well:
Success in the Land of Suits
I must say that I probably mention this career choice too often, because it often strikes me that there aren't enough of these to go around. However, every company that supplies a product or service needs scientists at the MS or PhD level to head out to customer laboratories and help them. They conduct seminars, they do one-on-one training, they support the sales staff in trade shows, etc. One of our posters, John G. Hoey, is a successful sales guy now, but I believe that he started his career as an Applications Scientist. I've also written him to see if he can tell you more.
