    Are you sure you understand it right ??? What do you mean by 'linux 
consider it secure' ?? do you mean it has no access control by default 
???? This happens with ALL linux network (logical and phisical) ones. If 
you need access control on network level, then you got iptables !!!

    What was the problem solved/workarounded ???? Tell us what happened 
and maybe we'll tell you if using rinetd was a smart solution and, if 
it's not, maybe give you other better workaround tips.

    No seek and hide games .... tell us what's really your problem please.

    Do you mean loopback interface to throw/receive traffic on your 
phisical network, ie, ethernet cables ??? If this is your idea, it goes 
against the whole loopback idea and i think it certainly cant be done.
