I've had to use it when there were vendor interop-problems, the LDP 
session wouldn't come up otherwise. I even posted to the IETF MPLS list 
regarding the fact that I couldn't figure out where in the standard it was 
said what address should be used where, but I received no reply so I am 
still none the wiser how it should work so I know what vendor to tell to 
go fix their stuff.
