They have the wordcount widgets up and running at the NaNoWriMo website. I've put the basic Participant Widget in the sidebar on the right.
I like the My Month widget, but it's not working now, so I've taken it down.
Obviously, I need to write more today to reach my goal. I'm currently at 16,327, and I need to reach 16,667 today. I only wrote 362 words this morning before work.
