Several influential people I know of share that view, though with different
justifications in some cases.  In spite of the EMRED error Randy reposted
earlier (A host is a host from coast to coast...) the fact is that at some
strata, traffic *does* tend to stay local.  Certainly a workstation has more
to say to its local file/mail/news/whatever servers, on a counted bit basis,
than it has to say to more distant servers of any protocol.  (Here, "local"
is defined primarily as the LAN but is intended to sweep the "campus" or
even "corporate Intranet".)

Conventional thinking is that beyond that threshold, if a workstation wants
to trade packets with some host outside the local administrative region --
that is, something out on the "public internet" -- that there is no blip on
the histogram for servers in a campus or intranet which is topologically
close to theirs.  The flat rate (per distance if not necessarily connect time
or packets sent/received) pricing paradigm that dominates the North American
internet market gives no _cost_ incentive for getting something locally if
there are also copies of it to be had "long distance."

There are, however, performance and reliability incentives for avoiding the
long distance links if you know that there is a way to do it and still reach
your objective (another copy of GNU Emacs, or an X rated GIF, or whatever.)

I would like to know if anyone has measured this one way or the other, since
if there is a demonstrated tendancy toward local traffic, it may open some
currently-closed minds on the value of joining *hundreds* of regional IXPs
and regionalizing our routes so that we can inject a subset into each such
IXP without giving anyone unintended transit or subsidizing their long haul
