Only bogon list will catch some real-time hijacking and only when
they are doing at the unannounced space (which does happen - see
presentation at couple nanogs ago about spammers announcing full
/8 and using unallocated portions; there were other cases too
that did not use as large of an announcement).

The real-time hijacking (short-announcements that go away in about
an hour although some do stay longer) of someone else's space or 
short-term announcements of unused legacy space can only be caught
when you know where correct announcements should come from and until 
we have SIDR, there is no reliable way to do it. The way i'm testing
it is by comparing where routes for where announcements come from
before and setting certain time period before route is considered 
"adequate" (this has obvious bad implications for those changing
from one ASN to another). If my project get sufficiently stable for 
public consumption trials I'll let you know more but from what I
wrote you should get an idea on how set something like it yourself
(and I think this is something similar to what others are doing too 
already, I'm unsure if they are making data public or not).
