I for one am glad to have the option to choose. The sad reality is, there is no universal support to even nack AAAA DNS queries properly, which makes this necessary for most people on the internet today. It is sad, but the problems mentioned above are true. -- Todd Fries .. t...@fries.net _____________________________________________ | \ 1.636.410.0632 (voice) | Free Daemon Consulting, LLC \ 1.405.227.9094 (voice) | http://FreeDaemonConsulting.com \ 1.866.792.3418 (FAX) | "..in support of free software solutions." \ 250797 (FWD) | \ \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\ 37E7 D3EB 74D0 8D66 A68D B866 0326 204E 3F42 004A http://todd.fries.net/pgp.txt
