Just to point out: DP already has q2-based model support. The problem is keeping extra media distributed after people copy the map - ie: a server owner plays your map, then copies it to his own server... and he loses your custom texture/model, etc without knowing it. HL allows you to include the texture in the .BSP, but that's not always the best solution. I do think it'd be nice to optionally pack files on the end of the .BSP.
But you have to manually create the collision.
