I just discovered that IBM released (the source code of their Workplace Shell for Windows: Source code has been released under a proprietary "Workplace Shell For Windows" Public License - v 1.0 Togheter with BeOSWin (attached - public domain ? - sources), could be a good base for an alternative open source shell for Win 9x, IMHO. Hope that helps, or at least inspires ! beoswsrc.zip
