the recent postnuke forks might be a good thing, if the following two things materialize.
postnuke: The Embedded PN initiative will allow us all to leverage all the amazing pieces of php code out there in a fast and reliable way, by allowing client applications to work under PostNuke seemingly. This will hopefully become the PN applications server framework.
envolution: This whould more or less be a direct replacement for the current hooks (autolinks, wiki, and ratings) but would not replace hooks. It would allow for direct api calls to classes that provide functionality for any module to call if it is turned on by the site administrator. So for instance polls and comments could be loaded dymaicly and used within any module as a direct api call. This would allow the wite administrator to add polls directly to a news article. This would also allow comments to be used by any module that you want to allow to use them. For instance you could allow comments on your downloads. This is a small example of the functionality this could provide.
guess where those features will end up.
