I think we have one customer connection where their firewall admin
thinks "it is more secure that way" - read, we can't ssh in if we come
from high ports.

OTOH, thanks for the pointer with ProxyCommand - it's a very specific
niche problem with a viable workaround, so I can't think of any 
remaining reason why we'd want suid ssh anymore ;-)
