How much testing have you done?  I have never had a
problem with this, but then, I don't have to deal with
any huge datasets.

Why would you need to do this?  If you want to show
different data to different users, then you reference
the user name (e.g. current_user or session_user) in
your view definition.

Or you could just use unbound controls.  Not really
that difficult, but a lot of coding.  Most of us are
using Access in order to avoid all of that :-)
