For the 3.0 codebase, I actually implemented a way to subject FreeMarker templates to Java security policy. See <http://freemarker.sourceforge.net/docs-24pre1/pgui_misc_secureenv.html> for the description, under the "Running Templates in their own security domain" section. It's implemented and it works; if there's interest, we could backport this to 2.4 codebase. Attila.
