I'll second that request.  

Unfortunetly its not quite as simple as it could be, as there is not
'device' to register in the utmp/wtmp databases.  You could, however
either use a simple lock-dir to grab 'devices', a simple database (this
is what samba does
http://pserver.samba.org/cgi-bin/cvsweb/samba/source/smbd/session.c?only_with_tag=SAMBA_2_2
) or just somthing based on the daemon's pid.  

The standard used in samba's case is 'what does ftpd do' as to what to
put in the various databases.
