File transfering from mac to mac?

I have had my mbp for some time but now my father is getting a mbp. I would like to know if there is a program that would make it easy for me to drag and drop applications/music/and videos onto his computer once it gets in the mail. Or is there a way without a application. I have a .mac account would is there a way to use that aswell. I would have both computers hooked up to a wireless router or if its possible could both computers transfer files to each other via bluetooth? Thanks for taking the time to read over this. Let me know what is the best way and fastest way I could do this. Thanks

You don't need any applications to do this. Just connect the two via Target Disk Mode.

FireWire Target Disk Mode

I was wondering if that was an option or not. Thank you very much for the advice.
