Tim,
In that situation, you'd be best off using the Personal or Enterprise
edition servers, which allow access control based on different user
accounts.
What you describe with pre-compiled viewers makes it hard for non-malicious
users to accidentally interact with a system but doesn't affect the ability
of malicious users to do so, since the access control is not enforced by the
server.
Cheers,
Wez @ RealVNC Ltd.
