<p>The special address '[system]' will return a system channel if one has been defined, Or the first valid channel we find if there are no system channels.</p>
<p>This is used by magic-auth if we have no prior communications with this site - and returns an identity on this site which we can use to create a valid hub record so that we can exchange signed messages. The precise identity is irrelevant. It's the hub information that we really need at the other end - and this will return it.</p>
