I don't know what you mean "equality" and I'm not sure what I said that
made you bring it up.

The principle in tunes is to have standards, but they are formed by
agreement of all parties (communities of users), not by us (system

Global unique IDs. I had to figure that one out.  I don't know if they
will be required or not. If they are, I hope they will remain hidden as
much as possible.  And that they can be changed without too much trouble.

It doesn't seem too important right now, but when the time comes in my
opinion protocols should be invented on the fly to contain just the
information necessary.  Maybe a standard meta-protocol to decide on
special purpose protocols would work.
