Reading this thread really makes me wonder a bit... How can anyone even
contemplate implementing inheritable properties on the client side? A
server-side implementation of (strictly versioned!) inheritable props
would not require any new logic on the client, and it's the only way to
make such a thing work without expecting weird behaviour with different
client versions. I'd have thought that the mergeinfo saga would have
been enough of a reality check.

Regarding upwards searches and "bounded reads" ... anyone who believes
reading a datastore is cheap should try to write a fast, data-intensive
GAE application. :)

IOW, I completely agree with Bill Tutt's assesment and Greg's arguments.
Please try to understand the issues before assuming things.
