It seems odd to try to optimize the bandwith on the actual local lan as
we have a decent amount of bandwith to work with. The only use case
that I can come up with to support that is during unboxing and/or a mass
re-install. And I don't think that we're ready

I'm not arguing simplicity; just that we have to be aware of the
implications of having lots of XOs pulling from the server with some
overlap with this method, but we don't with XO-XO. We just have to
make the tradeoffs clear, and understand them.
Agreed. Given

Scott,
Rsync documents using 100 bytes per file, so that's 100M of core
required.
That 100 bytes per file is very approximate. It also increases quite
a lot if you use --delete and also increases if you use
--hard-links. Other options have smaller, but non-zero, impacts on the

Chris,
but your comment serves to prove another point: that firing up a
program that has to do a lot of computation every time a client
connects is something that's deeply wrong. And that's just for the
