In short, the entire DPI debate is starting to go on similar lines, and flogging similar horses, as the gun control debate Yes, dpi has great, useful applications (ddos mitigation and other security, for example). And it has bad / harmful applications (dictatorships doing dpi to catch political dissent). That says a lot more about inappropriate / appropriate use of dpi rather than dpi itself. Nothing at all in DPI that makes it wrong, deeply evil etc. -srs On Mon, Mar 2, 2009 at 6:47 AM, Roland Dobbins <rdobbins () cisco com> wrote:
