You'll still get to see a lot of it. On Monday, there will be information on how to view the Opening General Session online, in addition to the live blogging already announced.
Beyond that, I've been given the green light to announce that 40-plus Lotusphere presentations from the AD, ID, INV, and JMP tracks will be posted as podcasts to developerWorks during March 2007. I'll share the URL with you once I know where they will be posted.
