What would you like to see in an Advertising Network?

Whats your ideal systems that you think would work great in an advertising network?

If you had your say what would you suggest to different advertising networks currently on how they could improve their services or Bring new services in.

Not looking at affiliate networks or anything here. Things like PPC and such.

Nothing outrageous like $10,000 per click.


Personally I would like some Paid per uv programs put in. So you could put banners on your site and get paid $X per X visitors.

Of course that already exists but I would like to see it some of the big players of the Advertising world ( Like Adsense and such )

So what are your views on the few questions I asked above?
