What is the best way to exchange large files between a friend or two of mine? I can't email as an attachment because it's too large. Burning to a cd and snailmailing is impractical. There's got to be a way the two of us can connect our computers (like a network over the internet or something) so we can share our files with each other. Are there any programs to do this? Or is it as simple as getting trading our IP addresses and configuring our computers like a regular network? TIA for the help.
