Prediction is hard; Analysis harder

I do think this is largely an argument about something nebulous,
that "visibility" is not well enough specified for people to really
agree or disagree meaningfully.

In order to establish visiblity, I would think you'd need to resolve
that into a list of things a firewall or other intermediary MUST
be able to do, given a message of some candidate type (e.g., SOAP
or plain "REST" HTTP).  And that should be a "for all..." rule,
so that we're not talking about one exremely "visible" message
and lots of others with poor visiblity.

And then, since that intermediary's ability to do those things
will depend largely on the degree to which it has been prepared
to, you also have to look at the COST of preparing that visibility,
starting at some *established* baseline.  You need this check in
order to prevent inflated claims of capability.

Probably too much work...

Walden
