We control the client as well as the servers, so it all gets pushed at
once. :)
That said, we're starting to allow clients that aren't controlled by us
to talk to our grids. We'll likely re-bundle our configs into digest-able
packages for them at some point and then have flag days.

But I like this idea a lot. The tricky part comes when clients really
do need to modify something (# of mappers, heap size, whatever).
