That would be awesome! I think a short name for 'external-pwds', like
'ext_pwds' sounds good to me...

Yes, of course. Unfortunately I don't have an overview what keys are
already bound to something. Ctrl+V seemed to be available. But I'm open
for other suggestions.

I tested your new function on Linux (with version string: 'zsh 5.0.7
(x86_64-pc-linux-gnu)') and it works for me. I have also tested the
cases
1) The list is empty except the current shell (works -> no list only '~'
on commandline)
2) I start to type and then hit the completion button (works -> sublist
appears)

I have replaced the zstyle line as you suggested:

  zle -C term_list menu-complete _generic
  bindkey "^v" term_list
  zstyle ':completion:term_list::::' completer _term_list


I neither have a BSD, nor a Solaris machine, so I can't test it for
Solaris, or implement it for BSD...

Thank you for your awesome help Peter and Oliver.

Cheers,
Julian
