I came across this (old) article about how some of the unallocated
blocks are unuseable due to pollution, sorry if you've already seen it.

would be interested to know if the situation's improved since 1/8 was
debogonised.
There was a presentation by George Michaelson of APNIC (the /8 is used
by APNIC who are now doing most of the studies) at the IEPG attached to
the IETF this week:
http://www.iepg.org/2010-07-ietf78/index.html
These are similar to things presented at the previous RIPE meeting.
Unfortunately it doesn't plot the effort of any de-bogonising efforts
over time, but the situation with 1/8 is slightly different as it is
used in various places, rather than just blocked as a "bogon." The
current status is that the worst few /16s within the /8 are held back
from allocation, but other addresses are being assigned. For those the
debogonising efforts are likely to be the same as most other /8s
assigned to an RIR.
Cheers,
Rob
