thats fine if you want to use just one banner

but what if you have many forums/slots?
but what if you want rotating banners?
but what if you want campaign to stop after a certain date?
but what if you want campaign to stop after a certain # of impressions?
but what if you want to keep track of sales, etc?
but what if you want to change slots for a certain campaign? add/remove slots?

I can go on but I think you get the idea.
