Valve is trying to workout a means of getting community mods for the Left 4 Dead game onto the 360. Right now the biggest obstacle is that most of the mods out there are built for mid to higher end PCs. The Xbox 360 isn't either of these... it's much slower.

"The coolest thing we could ever do would be to take something that was made by the community and share it with everybody - including Xbox 360 owners," Faliszek said. "How that happens and what work needs to be done is a little bit complicated."
