If you start up Steam when you don't have an internet connection, Steam automatically goes into offline mode.
but it does seem to want to validate at some point. i unplugged my ethernet, rebooted and tried to play a game last night...no go. But if i log in first then unplug it, i'm fine.
maybe it only has to check once in a while, but it does seem to want to check in, so if i ever had to turn off my internet for whatever financial reason, i would likely be screwed at some point.

You must activate offline mode once when you are online.
