In general, the computer situation for special needs persons is getting worse. Fifteen years ago "Simple Finder" for Mac OS, or the short-lived GEOS for DOS, had very simple environments that would be accessible to most people.

So I can set up environments that will work pretty well for someone with special needs, or someone who grew up in pre-computer era (i.e. my mother). The problem is maintaining those environments.
I need to be able to connect, control and maintain their computer environment without any action at all on their part. I need, for example, to connect to my mother's Mac Mini while she sleeps.
