HookUp enables streaming and downloading of music and movies directly through the iTunes interface, allowing a user to play and download from every computer running iTunes in a remote network as well as the local network. HookUp also allows sharing with unlimited friends or users, and even remote iPhoto sharing. HookUp has an intuitive interface that shows who's connected and the libraries accessible. It also has an iTunes toolbar to download, monitor activity and access available shares. HookUp shares show up in iTunes, in the same way as local shares. The download capabilities are activated with the Download Plug-in, which can be purchased from the DOT.TUNES website.
