SSH v3 specs?

[sshdev at rednu.com]

Has any thought toward a v3 protocol spec been discussed 
elsewhere, and if so what enhancements are being looked 
at.  Is it too early to consider such things, or should we 
open the door to the new features a protocol update would 
bring?

More specifically I have been investigating working toward 
a more enterprise-friendly hierichical authentication 
scheme, but I have quickly realized the magnitude of such 
a change.  I have worked with LDAP/PAM, but there are 
parts of ssh that are not very interoperable with LDAP, 
such as pub/priv keypairs.  These can be stored in a 
directory, but it is quite a kludge to do so at this 
point.

Thoughts and comments appreciated.

Thanks,

Ryan
