Open sourcing would also require open sourcing all the development tools. Also open sourcing the original code while interesting to look at would be impossible to extend (not impossible but very hard). It would make the most sense to open source BWS (the basic workstation code used for the later version of Star) with all the tools. It had a ton of well written documentation that was all given to universities to use along with XDE.
