You are going to have to name them because the reason I suggested this is that 
I can't think of any. Even Cisco routers speak ssh these days. Also, as with 
telnet, shipping the server component is separate from shipping the client. The 
servers could all be moved to pkgsrc. Possibly with a new category called 
"insecurity" so people know everything in there is a bad idea. ;-)

sshd works fine with Kerberos. I threw away my RSA key pairs on my home systems 
years ago and turned on the ssh Kerberos options. It took a few goes to find 
the right options, and it works just fine. As I alluded to in my previous 
email, ssh doesn't support Kerberos host verification, but there are patches 
floating around the net for that, and the Mac OS X ssh has those patches (or 
equivalent) applied, so this would be ground breaking.
