so i was thinking about a RR like for more then just 2 outgoing addresses.

well i think that it will be smarter to use a RR based on routing system
and not squid acls and other stuff.
the reasons for that are pretty oblivious.
the routing system is running on ram + compiled code + smp compatible.
so no need to run any commands and to rely on some twisting and annoying
the higher levels of the ip on the 7\5 layers model from 2\3 to 5\7.

i am learning some bgp and other stuff but never had the chance to
actually implement a RR based routing on linux\openBSD\FreeBSD so if
someone will stand and will put here some nice rules to make it
available to all of those users who wants\needs this thing it will be
very nice of him.

i will try to assemble some things on it.
i remember it was based on marking the packages.
