Although we don't make custom versions of our software for specific customers, our software, due to its nature, is highly customizable by the purchaser. Neither the Cantwell bill, nor the DPSWG letter mentions this type of software product. Huh? Does the fact that Microsoft C or WinDoze contains run-time libraries and is "highly customizeable" cause it to cease to be a mass-market product? Read the bill more carefully; it doesn't say anything about required sales volume, and allows for telephone/etc support for installs and the like. It also doesn't say anything about "end users". As long as the *seller* doesn't customize it for each user, it's mass-market. BTW a "standard commercial channel" includes mail/phone orders. - Bill
