IP was designed a looong time ago. I think it's reasonable to
make (or at least allow for) some accomodation when networking
bandwidths have gone up by several orders of magnitude. (And
while we wait for IPv6 to catch on ;-)

application of most concern. I know that we have customers
who, for good or bad reasons, _do_ use NFS over UDP.

Different sysctls for different folks....
