Yes. In the existing approach, the applet signer's certificate
must be configured in the policy and supporting keystore in
order for the signed applet to be granted special permissions
(the ones listed in the policy).

The next version of the Plug-in (which will go beta early next
year) will verify the entire applet certificate chain if the applet
signer is not configured in the policy/keystore.
Verification will go all the way up to the root CA in the chain
and check if that root CA is configured as a trusted CA in
Netscape/IE.
If so, the user will be prompted if they want to grant the special
"AllPermission" (which implies every other single permission)
to the applet (binary policy decision).
