Is there an example of serving spot5 (2.5m resolution) imagery using Geoserver
- should I store the images as files or database - will be used as a backdrop (I have seen that on the Postgis mailing list that the feeling is store images as files)
- should I configure Geoserver to serve them as WMS or WCS (this would be on a WAN line speed 512Kb, probably might decide to have boxes on the individual sites (5 sites), as 512Kb line is shared with other apps
- each individual image is about 1gig
- how about using jtilecache to improve drawing of layers

More or less the idea would be:
* store your images on the filesystem, but make sure they are in a format suitable for fast web serving (see http://docs.codehaus.org/display/GEOSDOC/High+performance+coverage+serving)
* WMS and WCS are two different kind of beast. Do you want to serve
images people can look at or raw data people can use in their GIS?
If the former, WMS using jpeg compression, if the latter, WCS.
* at the moment I'd suggest using TileCache instead of JTileCache, since
the latter has not been used in production so far. But if you feel
like testing it anyways, why not, we would appreciate to know how
it worked for you.
Hope this helps
