The changes to the server to support kerberos-2 at are about 30
lines of new code in two files.

Simon's code: 36 files changed, 3321 insertions(+), 9 deletions(-)

Please consider:

 a) kerberos-2 at can coexist with Simon's code, should it be
    merged at some future time;

 b) Simon's code consititutes two orders of magnitude more change
    than what Markus committed;

 c) not all the developers are familiar with Kerberos and GSSAPI;

 d) Simon's code is still going through the IETF process, whereas
    SSH.COM's is very minimal (basically a cleanup of the protocol 1
    Kerberos support) and therefore less likely to change;

 e) being volunteers, our time is limited; and

 f) security problems have been caused in the past by large merges
