This needs to happen.
Imagine if PVK2 had support like Gmod or L4D2. Users put in custom skins, models, textures, whatever, and you just click Subscribe and it's applied to your game.
I imagine that it would be easy now that PVK2 runs on source sdk 2013, maybe.
I also think it would inspire more people to join the community, with new maps and perhaps game modes being made, attracting new people.
