It'd be nice if Emacs did have a predicate for "is there any network
here?"  But I don't know what that would look like.  That is, there's a
difference between having a local network (i.e., 127.0.0.1), and being
on the Internet.  

But if any of our tests require Emacs to be on a functioning internet
connection, they should indeed be guarded by something like the
`skip-unless' you propose.
