Hi, you may already know, but for the sake of information.
I was surfing for pd papers and found this http://pdcon.org/ for the conference in Brazil, but it's offline. There's a fancy, spammy pink page instead.
Sadly, http://pdcon.org/ is linked from puredata.info and from other sites too (including http://umlaeute.mur.at/Members/zmoelnig/projects/pdgst/pdcon09/). Couldn't check other sources.
