The other problem I see with this is that it allows me the have a character I can loot farm with and a character to play with. For example, I get one guy at NWAF barracks, and the other I play with. Terrorize Elektro as a bandit, finally get killed. Respawn on the shore with nothing. But wait!
I switch to the other server and gear up at NWAF. Logout, go back to chernarus. Now I'm geared and I get to go kill people again. Rinse and repeat.
I don't really see a huge benefit to this, but I can understand that some do, and that you want to build in enough flexibility to the DB to allow more features in the future. My vote is to not worry about adding this functionality, but thats just me.
