There's actually some rationale in the docs. Sorry, guys, daddy gotcha.

mentions slaves behind NATs or firewalls.

Another feature is that you can replace one slave machine for another
without changing the master.

But, yeah, the fundamental rationale is to enable slaves that you
can't reach from the master, and that the slave doesn't need to run
any services.

Just wondering, I think I never ssh'ed into a windows box, either.

On a more featurish argument, I implement custom slave steps which are
directly python, and that report back non-string data to the master.
And I prefer that to having to write error log parsers, like you'd
have to with, say, tinderbox. Yac.
