Orb sounds pretty neat, though I haven't yet tried it. They just released their software for the Mac yesterday, having been available for Windows for some time. According to their press release, the free Orb application and service enable the streaming of any media type from computers running Windows or the Mac OS, to any other internet-connected device including laptops, mobile phones, and even TVs connected to a game console. You're able to access all your music, photos, and video anywhere, anytime, without first having to download content to your iPhone or iPod touch. Nor do you need to upload anything. All media stays on your computer and is streamed directly to the remote device. Orb simply streams the content over the internet. The software for Windows or Mac is a free download, and the service is free. But you also need to get the OrbLive app from the App Store for your device. It costs $9.99, or you can try their free version, OrbLive Free, which limits you to three random pieces of media from each category. Apparently if you have a TV turner on your PC (but not yet Mac), you can even watch live TV on your iPhone or iPod touch.
