iTunes Home Sharing has been around for a few years and is a handy way to access your media between devices. One reader wonders about trying to use this service while traveling:
My setup is Apple based i.e. iPad/iphone/appletv2/airport extreme/imac. The iTunes Home Sharing works brilliantly. Is there a way by which I can retain the home sharing function remotely? In other words if I am on 3g and still use the be able to see the iTunes media as I would on the same wifi? I have seen various articles referring to vpn and then indicating that iTunes is not available through the vpn tunnel or through the airport extreme etc.
