The feedback I've gotten has said that it should be quite secure.   By 
disabling all services except one that is designed to be of limited 
utility (the Proxy) there aren't too many openings available for attack.

I got a few comments saying that the limitations of application-level 
were too great.  They cited slow performance, inconveinent (requiring 
password), and inflexability (only can use specific versions of 
software).  The proxy is usable and gets pretty good performance, and I'd 
rather have something too secure and unfriendly than a breakin.  ;^)
