1. A client can request any byterange it wants from a HTTP server.
   But the server is free to just ignore the Range specification and send
   the whole thing anyway.

2. One problem for lynx is, how should it keep track of partially received
   files across sessions and which already partially received file from a
   previous session corresponds to which URL?  Remember that downloaded
   files first go into a session-specific temp file which will be removed
   (at the latest when Lynx exits).

3. 'wget -c' already does it, for FTP and HTTP.

    And the EXTERNAL command, put in the development code by you Wayne, can 
    be configured to invoke wget.  Or ncftp.  And can do downloads in the
    background (if supported by the OS).  Maybe we should advertise it more
    :)
