All,
I'm designing a web app that at full extent will show both North and South
America, with the base map served up with Geoserver. I would like to have
the option of using shaded relief. Does anybody know of a wms out there
that provides hillshading (GOTOPO30?) that OFFERS A NUMBER OF SPATIAL REF
SYSTEMS, more than just 4326?
Another question: Will I be able to use Geoserver 1.5 to host my own shaded
relief wms, with a flexible choice of projections?
Thanks,
Steve

I'm not aware of any, but never really searched.
Yet, I'd suggest to perform hill shading with a separate tool and then
save the result in a format more amenable to web serving that gtopo30,
a tiled Geotiff with overviews for example.
Serving directly from GTOPO30 with on the fly hill shading is going to
be slow on any system imho.

Yes, that should work. You can reproject your data in all projections
that the EPSG database knows about (some 3000 and more).
