What no horns? No cloven hooves?  No pointy tail?

Easy, My policy is to not propogate any customer routes unless they
are properly registered in the routing registry.  But how do I check 
that I have a "working" BGP peer up unless I can actually exchange a
route?  Here the testroute comes in real handy.

See above. And besides, is not part of RFC 1597.

Not a problem

Darn!  I was in it for the praise and adoration

You forgot the guys who register their net10 with a policy of "don't route
per RFC 1597.

I don't think this is a problem in the RADB.  We can take this offline 
to reduce my public exposure.

Yup again.

Only when it pertains directly to the RA maintained route servers.

Nope, this is really good.               
See you in Danvers... :)
