I respectfully disagree.  I think it is a virtual certainty that if the
WSS protocol is useful, it will be used in ways far beyond its original
intent.  I don't think it would be wise to artificially constrain the
applicability of a new protocol by claiming that casual users are not
'legitimate'.

I don't know exactly what you mean by "custom protocol", but WSS is
*exactly* the kind of protocol that [1] was talking about.  The
introduction uses "XyzConsortium" as an example, but you can think "WWW
Corporation" instead.
