We just started preparing a YAPC Brasil 2008. It will happen together with CONISLI 2008, at São Paulo (http://www.conisli.org/), October 18-19. Yes, that's very little time until the event, but we'll make the best we can with our distributed efforts. Brazilians are known for being good at improvising. (But we'll work hard to make that work in this limited piece of time.)
We know we will have a stand and a room where the talks will happen. Everything else is in flux yet. We are going to try to put down a preliminary scheduling very soon, and we would appreciate contributors as speakers and people with good ideas and suggestions.
At first sight, it is quite possible that we can gather together many Perl developers that never meet one another in person. That's mainly the people who keep busy the mailing lists Cascavel-pm, Rio-pm, and SaoPaulo-pm.
We are assembling a preliminary list of talks
I will try to post more information on the event as it is available.
