No, ccache does not support distributed compilation, unless you use a cache
directory shared over the network (e.g. using NFS), which I assume you could
use for your compiler cache as well. Are you thinking about sccache, distcc or
Icecream?

Yes, to the point that it will be an almost completely different program.
