this sort of address structure around an easily aggregated geographical
area, say the San Francisco Bay Area in northern California. I brought the
idea up about 6 months ago and it floundered due to disinterest, but it
still seems to be viable.
However, as Andrew w/UUnet pointed out some time ago, you end up providing
transit in this way.
If the goal is to only announce 195/8, any provider numbered in that block
that is dual-homed with this "deviant CIX" and some other provider suddenly
starts providing transit for the entire "deviant CIX".
I highly doubt that this is desirable.
