The caveat is that Netflow is useful for this purpose on a
smallish test/research network, in which port numbers and/or
combinations of port numbers and server addresses correllate to 
an application, which is what I happen to be doing.  Naturally 
on a public backbone you'd want to substitute "port-specific" 
for "application-specific".
