No, the plugin is built directly on top of WordPress.
I talked to JJJ about weekly dev chats last night and we would definitely like to revive them. http://bbpdevel.wordpress.com/2010/07/19/weekly-dev-chat/
Anyone and everyone can contribute to the project. I’ll be making some announcements soon on how people can get involved.
We’ll be working on bbPress as a WordPress plugin leveraging custom post types in WordPress 3.0+. There will be a direct/easy way for you to import your bbPress standalone data into the new WordPress plugin.
