AFAIK group dialout gives you access to the serial ports with their
modems, and dip gives you access to ppp's configuration files. These
enable you to configure and instigate connections, but that never
had any effect on users, who can all use the IP link once it's up.

To block a group, I think you'd have to use a packet filter to
drop their outgoing packets. Take a look at
under the heading "owner".

OTOH it's easy to voluntarily block some browsers from being able
to make non-local connections, eg:   lynx -localhost
