re: "Are you aware of any such cases?"
Before I run too far afield of my main point, it's the LAN closets right no=

You can't lay your hands on equipment that's no longer in existence because=
it's
been eliminated, for starters. This is probably the most important point to
grasp. There is no LAN equipment on site anymore once you've backhauled your
desktops directly to a central site over optical channels.
And to do this, fiber to the desktop (and a generous smattering of WLANs ne=
ver
hurts) must be considered first, no longer brought back to the local closet=
, but
rather to one or two central locations that could either be in-building or =
to a
nearby data center or colo. Or as far away as applications will permit. Tha=

sentence should serve as evidence that I've learned my lesson ;)
Some enterprises (including several large federal government agencies) have=
done
parts of what I'm referring to, but none that I am aware of has done it all=
. By
the same token, nothing that I've mentioned has NOT been tried somewhere by=
some
enterprise before, which is to say that every aspect of fiber extension tha=

In the large enterprise space we've already seen, time and again now, how l=

VPNs also come to mind. Think: FiOS.=20
Why would supporting the desktops of a 1,000 or 10,000 employee company, wh=
ich
desktops would be scattered over a half-dozen or a hundred urban and exurban
sites, be any different than supporting the same number of residential
subscribers who are being supported by fiber to the home?=20
Indeed Verizon has already deployed the equivalent of FiOS to some federal
government agencies, while holding back in the enterprise. I suppose they a=
