We could conceivably simplify this even more.  We could simply have a
boolean field indicating whether a note is public.  If it is not
public, then system:sharing:read*:user email com would be checked.

Then we could add a public field to the Note object in the API spec (I
forget if this is already in the draft; l.g.o is down right now).

Is there something I'm not thinking of that would cause this approach
not to work?

Why readonly?  Why not read?  Were you thinking of having readonly,
edit, and readedit or something?  It seems easier to just have read
and edit, as separate tags.
