I may be wrong but I always thought hp-scan is also open source and is simply using SANE to do all the real work, as written here http://hplipopensource.com/hplip-web/tech_docs/man_pages/scan.html So you don't have to wait for less demanding projects to use it :) The real question is why your results are so different with different front ends on the same SANE installation?
