(1) Find out whether anyone has a clue about how to add more major 
    exchange points and actually usefully use them in their routing fabric.

But anyway:

I was looking at the Tech Data catalog (we've been very happy with a 
$3k 24-port 3com Etherswitch we got from them).  I found:

Digital GIGAswitch platform with a 2-port FDDI line
card; switches up to 3.6Gbps, forwards at 290kpps per
port, 11 slots, FDDI point to point and ring connections,
future ATM ready......................................... $30,000   $21,784

GIGAswitch 2-port FDDI Line Card, hot swappable.......... $ 9,000   $ 6,525
GIGAswitch 4-port FDDI Line Card, hot swappable.......... $12,500   $ 88085

A backup switching proc. is $15k, a backup 20amp power supply $2k.
Last time I was at MAE-East, I only remember < 20 ports on the Gigaswitch.
And there's no generator @ MAE-East.  And I'm not sure that those batteries
mean diddly.  In Philly, the batteries are for DC only.  @ MFS, we're on
our own for AC backup.

Anyway, with some etherswitches with FDDI uplinks and a GIGAswitch or
two, you're off.  I don't have list prices on the Catalyst series...

Then, as mentioned above, NOC & telco facilities, and you're off.
We're talking with an IXC about taking an OC3 from Pennsauken to
NYC and handing FDDI off for $4k and Ethernets for $2k @ 60 Hudson.
We ourselves don't have an interest in it, but hey...

Of course, an extended NY Nap that hits 60 Hudson, a building in Philly,
and Pennsauken could be interesting...  I don't know how crazy a mac-level
bridged medium like a bridged FDDI in 3 locations many ms apart would
function.  And the technology they're thinking of using doesn't scale well - 
Netedges speaking to each other over OC3s.

But if they can get 4 customers @ $4k per, they'll do it.
