This is exactly what we are considering right now. I think we need to bargin
with the teleco based the estimation of our bandwidth. We can always get the
dark fiber when requirement comes, it just a matter of how soon and how
much.

Definitely, unless we could get two pairs, which is not practical for an
end user.
Based on you guys great inputs, I think we probably will intend to rule out
the the dark fiber solution, it is kind of like rent a backbone from the
carrier, if the carrier heavily oversuscribes the backbone(through ATM
etc.), they are unlikely give the end users a very cost-effective price.
