I misspoke.  It isn't necessary that it have any state in order to form
a representation.  Identity is sufficient.

When you click on a mailto: URI, the action that is taken is
equivalent to GET.  It could even be implemented as such, using an
intermediary that returns a form for composing an email.  That form,
or the "form" that Eudora/Outlook/whatever pops up when you click on
the URI, is a representation of the resource identified by the
mailto: URI.

Why not?  I could imagine a representation that included information
such as who the adminstrator was, information about the machine (OS,
CPU, etc..).

What it identifies, an IP stack, could have a representation.
