A year, or more, ahead. For larger spaces, often two
or three years.
2010 + 2 = 2012...
Eh, it's relative. Moscone frequently accommodates 10-20 thousand
people at a conference. But because they are so large they often have
spare capacity. I've seen people book a small portion of Moscone
(several rooms) for 500 people on only four months notice provided
they weren't picky about the precise dates. You can end up having a
small gathering in the shadow of a much larger one, but it certainly
possible to find some spaces on short notice.
However, if one is talking about a bid for Summer 2011, that should be
more than enough lead time that one shouldn't have to worry too much.
