What become old biology tools?

One of my colleagues remarked today that a lot of old biology software tools and libraries are designed by academics and abandoned as soon as their interest (and funding) switches to something else.
So it is very dangerous for a community or a business to rely on this kind of tools, as when something goes wrong there is no expert in sight ready to offer an helping hand.
I wondered if something could be done to improve this situation. At least a list of such abandoned biology software could be maintained.
