Sorry, I am not asking about OpenSSH. I know about OpenSSH, since
I fixed many bugs and added protocol 1.5 and 2.0 to OpenSSH. And
yes, OpenSSH is no 'clean-room' implementation but is derived from
the original ssh-1.2.12. This results both in benefits and limits.
There are no usage or re-usage licence restrictions on OpenSSH.
