There is pressure for consolidation in the existing markets, yes. At the 
same time I suspect that the level of provider care and attention to some 
of the common issues, including routing table size will decline due to the 
price pressures on the providers.  We saw in V4 that the most basic form of 
routing bloat pressure was from inattention to routing detail - these folk 
were in general not malicious - they were simply following the templates 
left by the original installers. This is certainly a more significant risk 
factor in an increasingly commoditized  provider environment. (Its not that 
they won't care, but they they'll find it harder to fund caring)
