no but:
chars with the same IP in the same time will be transported into admins room ( nice one with jail skin

) ) and there some sort of test...
example..
Starring: Admin as a master one
char A - Sam
char B - John
Admin: hey ar Sam turn around and dont stop!
Admin: and you John dont stop to talk with me and answer my Q ...and dont stop to talk and answer my Q
after 1 minute:
heeey Sam...turn around faster....and dont stop that nice movement with your ass
and you John what is your favorite NPC in Fallout 3
after 4min....
when all is ok than char will be teleported into location admin choose, some save town
when not...jail is near

because: when alting on the 2 comp at same place it is hard for one people to turn around at one keybord and answer Q on the other keybord ( here could be some else command as turning around because of it could be done with some hard and thin object place on the key ">" )
I dont know if there is possibility to run FO at 1 computer(1 windows) at some time , there will be hard to turn around and answer at the some time... it is nearly impossible , maybe with some special program ....

)
but if someone play with 2 comp in the work or home and have comp near each other, admin control with turning and answering should be cheated as I described
trully I have 2 comp as I described, but ALWAYS I have logged only 1 char at the same time.... so logoff char A and login char B at the same time
