This is a host-based solution and would work for all connections that
invoke a logon UDC on the 3000:

  ...
  setvar numjobs JOBCNT("@s:!hpuser.!hpaccount",ses)  # find all sessions
                                                      # logged on as "you"
  setvar ipcnt 0
  if numjobs > 1 then   # there is at least 1 other session logged on as
"you"
     setvar i 0
     while setvar(i,i+1) <= numjobs do
        if JINFO(word(ses,,i),"ipaddr") = HPREMIPADDR then
           setvar ipcnt ipcnt+1
        endif
     endwhile
  if ipcnt > 3 then
     echo You have too many sessions logged on as !hpuser.!hpaccount from
the
     echo same IP address (!HPREMIPADDR).
     bye
  endif
  ...

Note: I have not tested the above at all, but I hope it conveys the
general idea.
