One time provisioning over http without server

I've searched the docs, forum and Google for a way to do a one time provision but have only found information on doing it manually through the phones web interface and linking it to a provisioning server.

I don't have admin access, only user, and I was hoping to set background image, ringtone, push credentials and poll credentials over http. I'm able to do it manually, but I'd it possible to do it through an app?
