As part of a general preservation effort, This now exists:
We are aiming to save all software that compiles and runs under BeOS PowerPC. Where Source is available we will put up that source. Where development will carry on, a distinct repo will be created, where is is pure preservation it will go in to a group repo.
If software has no source code we plan to package it and make it available as assets against the project. The main github.io page will provide categorised links to make it possible to find the software.
This is a labour of love and anyone who has a BeBox, or PowerMac, that runs BeOS is welcome to help out.
We also hope to host newer packages if/when we get the modern GCC port based on Retro68 working fully.
