+So far...
+
+ssl3.netscape.com:443 does not support client side dynamic
+session-renegotiation.
+
+ssl3.netscape.com:444 (asks for client cert) sends out all the CA RDN
+in an invalid format (the outer sequence is removed).
+
+Netscape-Commerce/1.12, when talking SSLv2, accepts a 32 byte
+challenge but then appears to only use 16 bytes when generating the
+encryption keys.  Using 16 bytes is ok but it should be ok to use 32.
+According to the SSLv3 spec, one should use 32 bytes for the challenge
+when opperating in SSLv2/v3 compatablity mode, but as mentioned above,
+this breaks this server so 16 bytes is the way to go.
+
+www.microsoft.com - when talking SSLv2, if session-id reuse is
+performed, the session-id passed back in the server-finished message
+is different from the one decided upon.
+
+ssl3.netscape.com:443, first a connection is established with RC4-MD5.
+If it is then resumed, we end up using DES-CBC3-SHA.  It should be
+RC4-MD5 according to 7.6.1.3, 'cipher_suite'.
+Netscape-Enterprise/2.01 (https://merchant.netscape.com) has this bug.
+It only really shows up when connecting via SSLv2/v3 then reconnecting
+via SSLv3. The cipher list changes....
+NEW INFORMATION.  Try connecting with a cipher list of just
+DES-CBC-SHA:RC4-MD5.  For some weird reason, each new connection uses
+RC4-MD5, but a re-connect tries to use DES-CBC-SHA.  So netscape, when
+doing a re-connect, always takes the first cipher in the cipher list.
+
+If we accept a netscape connection, demand a client cert, have a
+non-self-sighed CA which does not have it's CA in netscape, and the
+browser has a cert, it will crash/hang.  Works for 3.x and 4.xbeta
+
+Netscape browsers do not really notice the server sending a
+close notify message.  I was sending one, and then some invalid data.
+netscape complained of an invalid mac. (a fork()ed child doing a
+SSL_shutdown() and still sharing the socket with its parent).
+
+Netscape, when using export ciphers, will accept a 1024 bit temporary
+RSA key.  It is supposed to only accept 512.

+The February 9th, 1995 version of the SSL document differs from
+https://www.netscape.com in the following ways.
+=====
+The key material for generating a SSL_CK_DES_64_CBC_WITH_MD5 key is
+KEY-MATERIAL-0 = MD5[MASTER-KEY,"0",CHALLENGE,CONNECTION-ID]
+not
+KEY-MATERIAL-0 = MD5[MASTER-KEY,CHALLENGE,CONNECTION-ID]
+as specified in the documentation.
+=====
+From the section 2.6 Server Only Protocol Messages
+
+If the SESSION-ID-HIT flag is non-zero then the CERTIFICATE-TYPE,
+CERTIFICATE-LENGTH and CIPHER-SPECS-LENGTH fields will be zero. 
+
+This is not true for https://www.netscape.com.  The CERTIFICATE-TYPE
+is returned as 1.
+=====
+I have not tested the following but it is reported by holtzman@mit.edu.
+
+SSLref clients wait to recieve a server-verify before they send a
+client-finished.  Besides this not being evident from the examples in
+2.2.1, it makes more sense to always send all packets you can before
+reading.  SSLeay was waiting in the server to recieve a client-finish
+before sending the server-verify :-).  I have changed SSLeay to send a
+server-verify before trying to read the client-finished.
