I _think_ that this problem can be solved by simply never advertising
to your neighbors that you have a block.  Instead, make up a few 
"loopback links" that point back to yourself and then use them to
pad out messages to at least 3 hops.

This would prevent people who were directly connected to you from 
finding out what you've got in your cache.  (I think.  I haven't had time
to check it out, but I think there would be a way for someone to connect 
to you with three different clients and compare what routes you were
advertising to get more info.)

It's a simple concept, but hard to explain without pictures.  Should 
I draw some?
