Is this idea completely wrong? Yes. Fortunately, knowing this, you can adjust your expectations and your development plan. :) Cheers, David. -- David Fetter <da...@fetter.org> http://fetter.org/ Phone: +1 415 235 3778 AIM: dfetter666 Yahoo!: dfetter Skype: davidfetter XMPP: david.fet...@gmail.com Remember to vote!
