Short TODO list.  There sure is more things to do.

   - Make server really >2GB proof.
   - Implement a server library that can be integrated to
     other programs.
   - Add timeout parameters to client libraries.  Or at least make
     read/write calls to fail if server seems to be jammed forever.
   - Implement connection timeout in server side at least for
     situations where server has pending writes and client doesn't
     seem to read it in reasonable time.
   - Password exchange mechanism that doesn't reveal password to the
     eavesdropper.
   - Protocol version 1.1 with encryption.
