Campaign file protection ?

Hi all :)

I'm working on a campaign with many models inside and i want let people download the beta. But i dont want this people can steal models, skins and sound before i put online the final version.
The final version will be opened so i dont try to prevent the use of my stuffs.
I know heavy locker.. and about deleted listfile.. but all the stuff are available in the campaign window importer after that..
Anybody have an idea ?

we are not allowed to discuss how to protect maps/campaigns here
o and as a general rule, even if you protect your map with the most strongest map protector ever, people will still be able to take models out of it, any map that is protected can be unprotected. so if you dont want people to take the models, i suggest dont release the beta at all.
