aprsdigi:
  - add "dupe without modification" flags so that all received packets on
    a particular net are retransmitted to a particular net as received. 
    Useful for udp for example so all packets heard on ax25 intf can be
    repeated to LAN/multicast listeners.
  - add file: and/or tty: intf type to support non-KISS-capable TNCs (this
    is getting gross).
  - Combine unproto() and parsecalls().
  - make log file list rx/tx port and timestamp?
  - Figure out why I can't just use standard full_sockaddr instead of
    struct ax_calls.
  - add maxhops for TRACEn-n. (I don't remember what this means!)
  - Now that we've done udp, add tcp.
  - assure 100% alignment with APRS Protocol Spec 1.0:
  - add a real config file instead of hokey command line switches.
  - add IPv6 multicast, IPv4 SSM?
  - suppress loops/dupes per-interface???
  - Implement HOME: (or did this idea die out?)
  - Implement compressed and/or decompressed GPS strings and posits.
  - Look at my notes from DCC proceedings APRS papers.

mic_e.c:
  - Add PIC-E support: /P>mon
  - Is this necessary anymore given aprsd?  Look at putting kernel ax25
    support into aprsd.
  - Try to understand javaGate, get the latest version, and see if it's
    still OK with Alan to bundle it with this distribution.

General:
  - Make a new distro rpm and tarball.
