I have a client looking to deploy advertising to the websites of their subsidiaries.
Some research and a demo install later showed OpenX http://www.openx.org/ to be the clear leader for open source solutions using javascript.
Then they threw in the wrench that some of their subsidiaries use Myspace for their primary web presence, so they'd like to be able to deliver ads there as well. That means a platform that would deliver ads via a flash widget.
I haven't been able to find any open source flash ad content networks.
Anyone have any experience delivering ads to myspace? Help would be greatly appreciated!
