Ah.  I didn't know that.  Thanks!

You're right: those are serious drawbacks.  If folks are going to do
this, then they need to do it right, which means making sure everyone
is in the loop and making sure that support staff are clueful/diligent
enough to investigate -- or at least hand off to someone who'll investigate.
This stuff works but only if you're adaptive/flexible and willing to
learn and adjust on an ongoing basis.

And as someone who constantly beats the "Internet != web" drum,
I second this.  Marginalizing other protocols doesn't serve us well
in short term (it breaks things) or the long term (it stifles innovation).
