Agreed, for the most part, especially when one is solely dependent on the 
incumbent carriers. I should point out, however, that some commercial enterprises 
are leasing their own lambdas from dark fiber providers who are running native 
GbE  on their regional routes, both linear and ring-based, and those nets are 
becoming rather expansive. One such network that I am intimately familiar with 
now encompasses six northeastern states, and counting, adding segment after 
segment. Jitter on the larger ring circumferences? Yes, you betcha. Compensated 
for by either 3R regen or Layer 2 switching techniques or some other opaque-
inducing means. 

When such routes are actually available and justifiable, the business problem 
then centers on risk assessment. I.e., will those fiber carriers continue to be 
viable for the foreseeable future? And so it goes...
