I am certainly not one to forget where we came from.   It
did, and will, have its place in the network.  

However, more end to end knowledge is required in a converged
network.   I am for one looking to ease the load of general
traffic engineering.   In the giant carrier backbone, it
may be better to use your resources wisely, than to overbuild
your network.   

I hear a phrase quite often "Everything is going to IP".  Well,
before my phone call is on IP, I want some guarantee that its
getting from point A to point Z at the rate I'm paying for.

On the OXC front:

The usage that may become dominant, is more protocol agnostic.
The sales of point to point lambda windows makes for a pretty
cool application.    This looks more to be a "carrier-to-carrier"
application.   Rather than leasing dark fiber, you can just
buy a lambda to complete your ring...etc.    We might finally
have a good use for all this glass going in the ground.

And before I slip too far off topic....
