Yes, look up Google adsense "partners" there are about ten I think. Contact them. I was working on project the other day and I think I saw about 50 alternatives. So these "partners" are bad ass with adsense, but they are not so stupid as to have only one advertising client. I do not know how that interfaces with HP. My work in the area is million hit range so i do not know yet how it translates to way bitchin cool writers like you.
