exchange 2007 user segragation

ok so here is what i want to accomplish, let me know if its easily doable.

i want to create ou's with users that are in different companies.

each ou or list of users in the ou can not view the mailbox accounts that are in the other ou's.

in essence, each ou should have its own global address list.

please advise.
