Long term we might not want to marry keys to an IP. There are a lot of
situations where authorized clients wander between many different
netblocks. What if I secure my traveling salespeople's laptops using
UNIX and cfengine? The whole time they're away from the office they
can't connect to my cfengine server. That's bad.

I'd end up having to use ssh/rsync or something if not one some
pre-approved network (easy enough to detect with cfengine), and
re-invent the file copying "wheel" when I want to use cfengine's copying

I know Mark thought hard about the decisions he made in this area, but
maybe today's multihomed and wandering machines weren't considered when
making this decision?
