The timeline is today and tomorrow... this is not work, I took some days off to get acquainted again with coverages and what I'm doing now are basically exercises after studying the theory (can't think of anything better than doing bug fixes). > I'm working on > "org.geotools.image.mosaic" at exactly the same time.

No problem, you work seems quite interesting, I'm looking forward to have a look at it (I think I'll keep on studing coverage related stuff for some weekends in January to consolidate a bit my working knowledge).
