Connected in so many ways

In preparation for siggraph, I've established identities in a variety of media:
dodgeball.com: finding friends via cel phone
flickr.com: photo sharing
the siggraph wiki

I'm taking a fairly rad but clunky camera with me -- the Nikon Coolpix 990 -- and I plan to moblog like mad. Should I carry my tablet around with me? Will siggraph have free wireless access everywhere?
