Comic Book Viewer (with new extention)

I have many comics that my non-profit organization owns these are not famous comics such as the ones of marvel or DC but are similar. I am looking for ideas on how to share these comics with others. All of the comics can be viewed with programs like? <[login to view URL]>? however, I am looking for my own extention eg: .edu rather then cbz for my comics, so my comics can only be viewed by one viewer that I own and can handle only my comics. Any ideas?
