Our school has 10 iBook G4s which we would like to put into a wireless peer-to-peer network. We do NOT need or want internet access; we only want to be able to use networked versions of reading and typing software. Will we need a base station or wireless router, or can we simply designate one of the machines as the "server" and put the client applications on the others? I'm primarily a PC user, so I'm not familiar with Mac setups. Thanks.
