Also the '-j' (--jobs) option of distcc, which might be useful in crafting 
the '-j' value you use with make.

e.g. I use +zeroconf, and my set of available hosts changes frequently:

$ distcc --jobs
9

$ echo make -j$(distcc -j)
make -j9

# I only use Zsh, but I think $(( math )) stuff works similarly in bash
$ echo make -j$(( $(distcc -j) / 2 ))
make -j4

Best,
