COD4 GOTY map sharing?

[asthmatic]

For the 4 maps that GOTY comes with, can my brother log on to my ps3 and use the maps or is the maps locked to a psn account. I haven't installed it yet, but i wanted to know the answer so i can give the ok for my brother to install it under his or my name account.

thanks guys
