Don't even consider server-side Office automation:

Thanks for that,
The program would only be used by about 6 or so different users, and
would be secured using a certificate and username/password
authentication. I'm not sure if that would affect the stability given
the small number of users, and I doubt there would be more than one
user at a time.

If you're referring to server-side Office automation, the number of
(concurrent) users is irrelevant - that's not what makes it unstable...
