i understand this ask and i resonate positively to it. however, i 
predict it will be seen as controversial in this community, based on my 
prior experience trying to get ssh/scp to support clear text for use 
inside a campus, datacenter, VPC, or VM server. i've also been trying to 
get an SMTP library's author team to have an option to ignore STARTTLS 
when talking to my own localhost. in each case i was told that the risk 
of accidental nonencryption across a wide area network was too great. 
so, good luck with this use case. --vixie
