Regarding the Tomcat SecurityManager, I've been working with that a little recently in an effort to identify the ideal configuration for shared hosting environments. The goal is to make shared CFML hosting more approachable/supportable by hosting companies.
If you are familiar with SecurityManager and have implemented a policy that works with Railo, I'd be *very* interested in seeing your policy file. Please feel free to contact me offlist if that would help! Thank you!
