I tend to prefer numbered links, since it makes it possible to cleanly 
test using ping that a circuit is up. With unnumbered, this isn't as 
easy, at least in cases where there are multiple paths to the remote 
side. Then again, I dislike Multilink PPP and IMA for the same reason, 
where circuits can go down without anyone noticing. Suppose I'd be more 
tolerent if I'd worked in an environment with good SNMP monitoring 
systems. :-)
