+<p>
+
+In later versions of this specification standard service names and
+interfaces for common services such as mail delivery and WWW CGI
+scripts will be specified.
+<p>
+
+<prgn/userv/-using applications and system services which hide
+<prgn/userv/ behind wrapper scripts may need to store information in
+the user's filespace to preserve the correct placement of the security
+perimiters. Such applications should usually do so in a directory
+(created by them) <tt>~/.userv/.servdata/<var/service/</>, where
+<var/service/ is the service name or application in question.
+<p>
+
+The use of a dot-directory inside <tt>~/.userv</> will hopefully avoid
+the user becoming confused by finding parts of a semi-privileged
+application's internal state in their filespace, and or discourage
+them from fiddling with and thus corrupting it. (Note that such
+applications should of course not rely for their global integrity on
+the integrity of the data on the user's side of the security
+boundary.)
