Yes, you certainly can use Flash with SCRIPTPROTECT. The two are not
really related. All SCRIPTPROTECT does is examine data from the
browser to see if it contains client-side executable functionality.

Not really. If you want people to be able to put client-side
executable content in HTML pages, that defeats the purpose of using
SCRIPTPROTECT. You could write a CMS widget to accept parameters from
the client and have that build a snippet of HTML that uses those
parameters with Flash Player, though.

That should not be a surprise. Again, all SCRIPTPROTECT does is limit
the ability of users to upload data that could later execute in
another user's browser. You might want to read a bit about XSS
vulnerabilities to see what it's supposed to protect you against.

All that said, SCRIPTPROTECT only provides limited protection against
those vulnerabilities.
