Hello PHIsquared,
Interesting suggestions, however in my experience, the KIVA school experience usually springs out of the action of one teacher who then might spread it to other classes. In most areas it is easier for one teacher to have a PAYPAL account with her class then to jump through the hoops of getting the school to open up an official account. Of course, the type of whole school account that you envision is something that might develop once a critical mass of individual teachers are involved.
I'm not sure if you're working in an education setting, but you'll probably realize that there are many fund-raising activities going on in schools. For instance in our elementary school this year, apart from the traditional drives (e.g. Terry Fox Run, UNICEF, Christmas Food Baskets) school groups have raised substantial funds for a school in Burkina Faso and sponsored a foster child. In my experience, once something becomes an official school-wide activity it is more vulnerable to being cancelled school-wide, whereas individual classroom activities can keep on going.
