This one was sent in by Brecht, aka (from IRC) Brecht, so I'll just quote him:
"BePorts aims to become a centralized collection of software ported to the BeOS platform. A 'BePort' basically consists of the BeOS-specific patches to the original source code. Along with a Subversion repository to store all patches, a Trac site eases cooperation on porting efforts. A wiki stores detailed information about each port. There is also a mailing list.
Head over to the website for more information!"
Thanks Brecht for the news and the site. Go check it out everyone, it seems like quite a good idea.
