on a side note, has anyone that's running any of these type of
monitoring services
performed any analysis or compiled any metrics on leaks? (renesys maybe?)

personally, i'd be sort of interested in seeing some stats on leaks such as:

origin (asn/network, country, common/exchange point)
duration of leak
size of leak
# of upstream networks that accepted the leaked prefixes
asn of networks that accepted the leak
# of incidents per network/repeat offenders
