Voting starts in March for the Drupal Association Board election.
Glad to hear that someone has taken this up. It would be great if nginx support was included.
To purge page http://mysite.com/node/1 from the nginx cache you just need to visit http://mysite.com/purge/node/1. The "/purge/" part is configurable, but that seems to be the convention. http://labs.frickle.com/nginx_ngx_cache_purge/
There are already two Wordpress modules that support nginx cache purging so a Drupal one would be great. (http://wordpress.org/extend/plugins/nginx-manager/ and http://wordpress.org/extend/plugins/nginx-proxy-cache-purge/)
