I prefer incremental changes as well. The only problem is that they
might not be sufficient to solve the current bottlenecks. It might
work if we restrict new users just to V.34 modem speeds. But if we
have *potential* new user growth with ATT Worldnet with up to 80 million,
@home with up to 50 million and the fast growing traditional ISPs,
(which show no signs of consolidation as far as I can tell) as well as 
widespread access speed increases to ISDN BRI, ADSL and cable, it may 
not be enough.

As Robert Moskovitz pointed out, even the growth in common used backbones
speeds is not keeping up:

1.       56 kbps    
2.    1.544 Mbps  increase by 24
3.   44.736 Mbps  increase by 28
4.  155.520 Mbps  increase by merely 3 

Just keeping in step with past growth patterns would require a step
to OC-24c at 1244.15 Mbps now, but there are no routers which come
even close to those speeds.
