Or better yet, just use peds.

Skin possibility # 2:
What if players upload skins through their registered account (needed to play) and they are checked for being innapropriate. Players skins are numbered (315) so they can be retrieved when online (loading skin 315.bmp directly from the server) Also, even if you are on somebodies server, you have to be connected to the main server, so from the website all servers can be monitored.

That put very disturbing ideas and visual concepts in my head.

Well, I would love to help programming  But I also have some good suggestions, and I also want to follow this mod 

What would happen if you entered a bus? It has "unlimited" passengers.

I don't know what you're doing about different skins now, but I have a couple plausable Ideas. If everyone has the Claude model and different skins, you can download them automatically from a game lobby (anyone with porn as their skin could be kicked or everyone could download his skin  ) OR you could choose from Claude or pedestrians. It could be in a config of sorts that when it loads the different people it loads their ped. It's not impossible to do, heck, even I can do that. Anyway, watcha think?

Hey guys.. I come in support of this mod 
If there's anything I can help with, I can do anything anything-wise. Anyway, can't wait to see the mod finished!
