Can Openx Display Ppc Text Ads Like Google Adwords? Options

[henry]

Anyone know if openx is good for displaying PPC text ads like google adwords (ranked by bid, results based on keyword search in search engine)?

We're looking for an ad system to do something similar to Google AdWords when users search for keywords on our search engine.

I've looked at others such as inclick, orbitscripts, inoutscripts, but they're either way too expensive, or too basic, or closed-source so you're locked in and screwed, etc...

thanks
