WRT, item 1 quoted below, not _all_ ISP's generate dynamic IP
addresses for their SLIP/PPP users. There are some that do, indeed,
assign fixed IP addresses. All that would be required to determine
if any of such an ISP's users are logged-on would be a rather straight
forward program (or script) that pings the corresponding address(es) and
maintains a list of all currently active users.
