I was thinking of something along the lines of:

void q_add(Q *q,PKT *pkt)
{
   // timestamp packet
   pkt->time=now(); 

   // add packet to end of list
   *q->last=pkt;    
   q->last=&pkt->next;
}

PKT *q_get(Q *q)
{
   PKT *pkt=q->first;
   if((pkt->time+q->max_time) < now())
   {
      free(pkt);
      return 0;
   }
   else
   {
      return pkt;
   }
}

No estimation at all. There are weaknesses in this approach, but it's simpler than adjusting a byte length.
