Kotaku reports BlizzCon had a panel today on how Battle.net and Starcraft 2 will be integrated. It uses one's email account to tie things together in some way. I post this here as eventually all of Blizzard's games will be integrated in a similar manner.
Looks like Starcraft map mods will be tradable across Battle.net
WOW Insider expands on the Battle.net features.
And Fahey shows off photos of Battle.net and Starcraft functions.
UPDATE: Kotaku reports Starcraft 2 can be played offline. You don't have to log into Battle.net.
