Multiplayer networking tutorials?

So I've become pretty script-literate, and have decent experience in a broad range of scripting topics. I think I'm finally ready to take that next step into uncharted territory.

Multiplayer networking.

Can anyone recommend a good series of video tutorials? I'm a very visual, hands-on sort of learner.

EDIT: I've found several online. This is actually way simpler than I thought it would be. No room for mistakes, but not terribly complicated.
