Is it possible to stream an iTunes library from one location to another device on another network? I'd like to stream movies from my home while traveling but cannot figure out how to actually get into my iTunes - or network for that matter.
If it's video content from your library you're wanting to stream, I wouldn't get my hopes up. Regardless of the method you use, your home network's upload speed is probably not going to be sufficient for video streaming over the internet.
No harm in experimenting though. You might want to take a look at Hamachi.
