inetd does the connection logging with syslog (when inetd has the
"-l" switch).

inetd.c has:
                if (lflag) {
                        syslog(allow_severity,
                            "connection from %.500s, service %s (%s)",
                            eval_client(&req), service, sep->se_proto);
                }

So if I understand you (and this) correctly, it looks like using syslog is
the correct way and using syslog wouldn't be reinventing the wheel.

Tell us more about your project.

(On a related note, this needs to be documented better in the inetd manual
page and I believe that manual pages for tcpd and libwrap need to be made 
or at least linked to /usr/share/man/cat3/hosts_access.0.)
