I mentioned this briefly in our F2F call, but I keep mulling it over in my mind so I wanted to put it in writing.  One way to work around the ancestor hurdle is to create a contract by flagging a specific property as "inheritable".  This could create a token (or something that functions similarly to a custom property) that cascades and it accessed by an inherited function.  Taking the previous example and converting it could look something like:

```
.foo {
  width: 100px !inheritable;
}
.foo > .bar {
   width: calc( inherited(width) * 0.5 );
}
.foo > .bar > .baz {
   width: calc( inherited(width) * 0.2 );
}
```
