After a quick overview of what it is these guys do for advertisers, we'll go into the whole "challenges" part. This is my first time moderating a panel, but I've covered them many times, and I've found that the best stuff comes out when the moderator brings a little bit of skepticism -- and even a touch of antagonism -- in the spirit of getting a good discussion going. So, I plan to ask the in-game ad network folks about the study released this year about low recall numbers for in-game ad spots. I'll ask the Popcap folks about building a name for their content, when it's a common and easy practice in the casual games world to knock off popular titles. I'll ask the fellows from Denuo and VPI.NET how much success they've been having pitching in-game ads, placements, and product tie-ins to more traditional advertisers. And I'll ask Major League Gaming who, exactly, is watching.

And this is where you, dear reader, come in. If you have any questions, antagonistic or otherwise, that you'd like me to ask, post them below in the comments. I'll post the choicest bits of the panel in next week's column.
