How about a Palamida for clean code?

The market for services to eliminate patented or otherwise legally suspicious code from products ia naturally limited. As is the market for finding simple bugs in code, where Coverity leads.

But what about testing code for its output?

Getting output from open source which is fully compliant with web standards like XHTML and CSS is a major challenge. Since the work of assuring such outputs is still hand-made, many projects are weak in this critical area.  

But shouldn't it be possible to identify the underlying code weaknesses using technology? Don't just tell me whether my output is compliant, tell me where I've screwed up.

And if we could do that, how about doing it with open source technology?
