Well, I just finished porting the admin scripts. The only thing left unported is removing files when a post is deleted. After that I just need to write up a php-createtable for doing a fresh install and then it will go into an actual beta release. Right now it's just snapshots and uncompleted.
Not sure of when it will come out of beta, as it all depends on how many people setup the beta and report bugs so I can get them all fixed.
