I don't know if this could be hacked into something useful for
internet-distributed cluster-style makes... it wouldn't be as fast as
farming out the individual dependencies, and is only as parallel-safe as
make -j is, but since all the preprocessing is done on the client, about
the only thing the servers need is a toolchain consistent with the
client.

maybe for a per-cluster basis with the dependency framework laid on top
of that...  :)

when I get my computer corner done I'll have to investigate this.
