There are currently three laptops that log on my home network daily. I have a 2009 AEBS and an AE that I recently purchased to extend my network strength depending on where I am. I have 3 external hard drives: 2 TB, 350 GB, 250 GB. I have Time Machine on two laptops. I'd like to store my music on one of them (not the 350 GB, as it's a Toshiba that doesn't like to always power itself like it's supposed to). I have a USB hub for the AEBS to plug all externals into. Anyways, ideally I'd like to access my music and have Time Machine running on both laptops wirelessly. A bonus would be to have the media (all from iTunes anyways) stored wirelessly and have read/write enabled for all computers to do. Then shared among all computers, obviously. Any tips to do this? I want to also make sure my media that is stored on the external is also backed up in Time Machine.
