Very nice. Cesar, thanks for the round up for those of us who couldn't make it.
Two comments, though, which aren't related to the topic but important nonetheless...
1) We are not the Open Arsdigita Community System anymore. It's the Open Architecture Community System now.
2) The GPL is not the public domain. It's actually rather explicitly the opposite of public domain. The GPL is copyrighted software, just released under a license that says that you must pass all the rights you have to someone else when you distribute it. Public domain means that anyone can use the software for whatever they like - as open source, free or proprietary software.
These may seem like nitpicks, but as marketeers it's important to present the product correctly, particularly in light of the OpenACS being free software.
