Leak detection is kind of on a different level. You need a bit more data to effectively detect them. ( I kind of know that).

It does provide a filterable live feed that we use for leak detection.

Apart from that we're using bgp.tools when we want to dig into stuff.
Oh, and most of the T1s have either routeservers or at least mostly usable
