Yes, definitely.  Convergence isn't all it's cracked up to be alright.. But it likely is also because of different design goals.

Convergence doesn't have to suck, it just does more so at the moment because we still have an amalgam of technologies dealing largely only with expression of convergence rather than convergence as an integral part of the technology itself.

And what you describe is a reflection of that.

Or that's what I think.

Although we may think IP is everything, Internet traffic is not the 
only type of traffice carried by telecommunication transmission systems.
If you take the entire cable system from a transmission engineer's point 
of view, it looks different than from an IP engineer's point of view.

Remember last year during the earthquake near Tawain, air traffic control 
and pstn voice capacity came back faster than Internet capacity.

Convergence isn't all its cracked up to be.
