As long as you've got consistent NIS services int he reomte site,
sure. You can even run an NIS slave remotely to stay mirrored to
upstream, and consider running the lemote repositories as read-only
repositories. But NIS is becoming really seriously outdated. And its
support for local root users to do "ypcat shadow" and then run
best-guess password crackers against the encrypted passwords is a long
standing security risk.
