what is it you are trying to leave behind that could not be more portably replicated by a collection of flac files?
Personally ill be happy if my children would listen to some of the music i like and remember me. my collection will not mean anything to them, nor should it.
You are correct! Not a technology, I'd just give them a list (eg. Shostakovich Piano Cto 2), maybe in the when 'when you read this I am gone' letter, though I would like to make it happen before then, so we can talk! ... and yes, that means do some work now.
also consider (Grand)^n(children)
Ideas about how to leave a 'repertoire legacy' would merit a new thread!
