Rotating Banners On Free Sites?

[MadMax]

I'm in the process of setting up the single coolest advertising tool I've ever worked with, PhpAdsNew. I know there are a few other users of this program around the boards here, so I think this is a perfect place to put this question up for opinions.

PhpAdsNew is awesome because it allows advertising of all types (from text links to banners of all sizes, etc.) to be delivered via php include to any page anywhere from a centralized ad server. In my case all my sites are on the same server, which will keep things from slowing down. It also tracks impressions and click through rates on all ads, which will allow me to target the best ads for each site and should overall give me a nice bump in conversions.

Plus, it will allow me to remove and add sponsors from a central location instead of having to rework dozens of sites should a sponsor go down permanently or screw me over.

My question is, how would the other link list owners feel about dynamic advertising on freesites submitted to them? Provided of course that there are no banned sponsors in rotation

It should be mentioned that I can still get most of the benefits of the program by using the program to serve static advertising...the dynamic ads would just be a bonus.

Interested in everyone's opinions, and thanks in advance.
