This is the question Breadbox should be asking it-self and take actions necessary to support the answer(s) obtained.
i) If it is a resource efficient GUI on top of DOS, then having links to FreeDOS plus a how-to page on getting the two smoothly working together would show a desire on their part to continue GEOS's existence.
A how-to page on getting GEOS to smoothly work on DOSBox, eComStation and other means along with a forum/wiki for hosting additional tips from users would also be beneficial.
If the underlying "DOS" is only required for I/O, then recoding the I/O functions for another OS might be all that is required to re-initiate interest? MenuetOS (or other minimalist OSes), if offering all the necessary I/O functions, might be a good to remain in the spirit of efficient resource utilization.
ii) If it is the user interface, then actions along the suggestion of a migration plan for user files - from the current DOS-based to the future OS-base - would indicate the will to continue in the future.
iii) If it is as a minimalist GUI-OS, then targetting a re-creation for a portable bootable USB Drive environment could be envisioned. In this case, community involvment under open-source or shared-source software development model would likely speed things-up.
