Subject: scp2 f-secure ssh communications ssh2 sftp scp1

The reason for the dumb subject line is that I've been searching on the
archives, and keep getting hints as to things that have happened
(history), but can't track down the answer. This should be easily found
in the archive.

scp1 (I may be inventing this name, for use in this e-mail) is an
'application level protocol'. In essence, it's rcp(1) running over ssh
(ssh1 or ssh2, I'm not too clear).

scp2 is another 'application level protocol': In essence, it's sftp
running over ssh2, but the user-level syntax is that of rcp.

OpenSSH (3.5p1 for example) has a command 'scp', which seem to be an
implementation of scp1.

The question I'm seeking a definitive answer to is:

Does openSSH have an implementation of scp2? If so, when can I find it?
