Ciao Jean, I am not sure which version of ArcGIS you are using, but looks like it is the one that relies on GDAL itself :-).
Gdal should allow you (us?) to elploit such geotiff, I am not so sure about ways to convert it with GDAL to something that GeoServer can exploit directly, like a multiband geotiff. I guess that the best thing would probably be to start including the GDAL geotiff plugin as part of GeoTools so that we could optionally use it in GeoServer to server geotiff as well, this should not be too much work using the gdal extensions, but I suspect it would not even be 1h work. Anyway, the reason that I have been excluding geotiff support from the GDAL extension has been that so far we have been quite able to do what we needed with the java version therefore I did not like the idea of mixing the two (and there also implications with the need for having native libs around, which is always a pain). Now with the support for statistics and RAT tables, I start to see the need for supporting GDAL geotiff directly. I am cc'ing the devel list to get some feedback from other developers.
