OpenX Hosted Solution Invitation

Yesterday, I got an invitation to try OpenX hosted solution beta . This hosted solution can serve up to 25 million ad impressions per month. If the “free version” is not enough to serve larger traffic, there will be premium hosted packages.
Compared to the self-hosted , it’s a little bit different. I installed independently few months ago. I haven’t decided where I will use my OpenX , but I will.
