Hmm... you *should* be able to do something like what's below (which is
rather simplistic, as a demo).  The idea is: if you're on the third word
or after, and the second word didn't have a ":" (so is assumed to be a
local file), then only complete remotely.

But actually I don't see how to get this to work in the case you're
talking about (hence the question marks), because the tag for remote
files is just 'files' so will allow it to complete local files.  This
looks to me like a mistake, and _remote_files should arrange for a
different tag.

I may be missing something, but if I'm not, changing _remote_files ought
to be easy.  There may also be other ways of limiting completion, but
the point remains.


scp_comp_helper() {
  if [[ CURRENT -gt 2 && $words[2] != *:* && ]]; then
    # Complete remotely only...?
    reply=('hosts ????')
  else
    reply=('hosts files')
  fi
}
zstyle -e ':completion:*:complete:scp:*:' tag-order scp_comp_helper
