Re: bbpress plugin 2 beta 1
@jerledb – Login/register are supported via page templates, there is a login widget, and eventually shortcodes too. A register widget is a nice idea but leads way to lost-password and activation widgets, none of which will make it into 2.0.
Spam isn’t really handled yet, since there’s no one spamming forums that don’t use software that isn’t released yet. 
There is a Trac ticket regarding Akismet integration, but either Akismet will need to be updated or a special version of Akismet to concentrate on post spam (which isn’t really a WordPress issue.)
Regarding IP addresses, there are WordPress plugins to help with this, and WordPress multisite comes with this kind of functionality baked in. Traditionally WordPress doesn’t handle spam at a user level, since registered users are typically already trusted to some regard. We run into this issue a little bit even here at bbpress.org. bbPress does log the IP address of every topic/reply that is created, so a plugin can use that to check against a ban list or something.
