Yes, in a perfect world you're correct, but the equipment which does
POTS<->VoIP is probably easier (and cheaper) to do if it has a static 40ms 
jitterbuffer instead of having to constantly adapt. Echo-cancellation 
probably is easier to do if delay is constant (which it is with constant 
jitter-buffer). OTOH the echo cancellation should be done in the POTS-VoIP 
interconnect and the echo is only present in the POTS part so that should 
work anyway.

But then again, that's why Skype is to successful, it adapts to network 
conditions, so it might be that this way will prove more successful.
