Now I have been pretty vocal about the whole MD5 thing, but I have to 
say that route-servers are probably not the best indication of 
MD5-ness.  Session which pass traffic get a little higher priority at 
most organizations.

Unfortunately, my organization was not passive until we got to see what 
the threat actually was, so our numbers are not useful.  Would any 
traffic-carrying-organization care to discuss their numbers?

And anyone want to admit seeing an RST-style attack?  Any attack which 
MD5 would have blocked?
