If I'm doing multiple unrelated Yocto based projects, and they use the

sstate-cache, and I only need separate build directories? (I normally put
downloads and sstate-cache next to my build directory, rather than inside
it.)
You can share BOTH the downloads and sstate-cache. You can safely share
sstate-cache between various versions of Yocto (OE) and distros,
machines, etc., it was designed just for that.
Our build server keeps a single sstate-cache for about 30 projects, with
4 versions of OE, 3 distros, and a dozen MACHINE configs. No problems
encountered.
In addition to that, you can share the whole thing ("tmp") for projects
that use the same local.conf and the same OE version. Building various
images for about 20 different machines with over 4 different
architectures (MIPS and ARM variants) in the same directory works just
fine and drastically reduces build times since they can share about
everything that's not unique to each machine.
