[...] Not so. (If you build your system in an optimal fashion -- which really does need a bit fleshing out, though.)

Nothing requires connections be killed using such deprecated addresses. -- Pekka Savola "You each name yourselves king, yet the Netcore Oy kingdom bleeds." Systems. Networks. Security. -- George R.R.
