distcc is great, and as I mentioned in that Reddit comment some of my colleagues are using icecream to great success.
I won't repeat my entire comment from Reddit, but one other notable point is that tools like ccache/distcc don't generally support MSVC, and we build Firefox for Windows with MSVC, so that's pretty important to us. And frankly, our Windows builds are slow enough that we can use all the build time wins we can get.
