You could take a peek at the pnm backend (not built by default out of security/privacy concerns, IIRC), but if I were in your situation, I'd start mostly from scratch as "legacy" code might get in my way. Have a look at the doc/backend-writing.txt file (it's a bit dated perhaps) and the SANE API specification is required reading, of course. The reason I mentioned the pnm backend is because it reads an image from file. Your web-base image acquisition scenario is basically just one step up from a file:/// URL. I'd have a look at implementing something on top of a generic URL fetching library or tool and provide a backend option to set the URL. No idea on what other backend options you might want to provide though.
