My father was given <2 years to live (CLL), that was 20+ years ago he is now 78 and in good health, still occasionally does treatments. Doctors had to keep amending the outlook and eventually admitted "who knows" because of constant advances in treatment.
To answer your question, if you have an estate plan which you probably do, I don't think it would be hard to specify an executor of the equipment, say the owner of a nearby high-end gear dealer you trust. They would at least know what the stuff is and could oversee liquidation of the gear, not to get the most money out of it, but to find new homes where it would be appreciated.
Better yet, maybe Audiogon could have an "estate sale" category, and you could specify some portion of the proceeds to your favorite charity or disease research effort in your honor.
It's funny, some of the equipment me and my friends have is so high-end or specialized that we sometimes say, "they will bury you with this", because of the unlikelihood of it being surpassed any time soon.
