- Stuff to implement:

  - Allow mtr to log the return packets, for later analysis.
    Done: 0.25 . Todo: allow the userinterface(s) to work while
    still logging to a file. Write a "logfile displaying" mode to
    mtr.

  - Request timestamping at the remote site.
       Andreas Fasbender has an algorithm that will allow us to 
       convert these measurements into one-way measurements, not just
       round-trip.

  - Allow mtr to also send larger packets. 
       This will enable us to get a feel for the speed of the links
       we're traversing. (Van Jacobson was working on this His tool
       was slow, mtr will rock with this feature.... :-)
       (Anybody have the statistics experience to tell me how
       to do the data analysis?)

  - The "don't probe all hosts at once" strategy can be improved a bit.
    It should not probe more than 10 unknown hosts, but the counter need
    not be reset at the start of the "round". This way if you probe
    slowly (relative to the RTT time to the end host), it can probe
    all hosts in the first "round". 
       -- DONE.

  - allow "keyboard navigation" in the GTK version. 



- Bugs to fix?

  - Do something useful if host couldn't be resolved. 
       -- Done. 

  - Revert to curses mode even if DISPLAY is set, but a problem
    prevents us from running in X11 mode.
       -->  The problem is that gtk_init simply calls exit for us if
            it finds a problem. Tricky! Suggestions welcome. 
       --> Call "gtk_check_init" when available. (i.e. new enough
           (1.2?) GTK version).

- Nice to have:

  - stop sending packets when a new host is getting entered. 

  - Show state ("looking up host") while doing the DNS lookup for a new
    host.

  - Read environment variable "MTR_DEFAULTS" as a commandline before
    parsing the commandline.  -- DONE. (ok it's MTR_OPTIONS.)

  - Autoconf 2.13 has a neat function that can be used to find the 
    res_init function: 

	   AC_SEARCH_LIBS(res_init, bind resolv, ,
	      AC_MSG_ERROR(No resolver library found))

    At the moment (march 1999) autoconf 2.13 is still too new to require 
    everyone to upgrade. About a year from now we can put this in....

  - Allow a toggle between hostname/IP number display. (for example a 
    click on the hostname could revert to ip number display in gtk version.
    curses: "n" key toggles hostnames/ipnumbers?
