As i understood him (unfortunately i've dropped the mail after
i've got the impression this will not make it anyway, sorry!) he
thought about something like

  myself at local-host$ ssh myself at host-over-ssh
  myself at host-over-ssh$ ~Copy_file path_on_local-host path(_on_host-over-ssh)

Why should this open a security hole, given that
myself at host-over-ssh has proper permissions for
path_on_host-over-ssh?  E.g., the session can do

  myself at host-over-ssh$ echo $(date) > path(_on_host-over-ssh)

The problem i see however is that there will be no filename
completion for at least path_on_local-host.
