I want to transfer some large photoshop files (about 500mb) to a friend over the internet. What is the best way to do this because uploading it to a site for my friend to download probably won't work because it is so large. I would really like something like ftp, file transfer used within the same network, or something that won't crap out or take ages (like aim). What do you guys suggest? (My friend is on a mac for what it is worth and we both have very fast connections.)
