I've never, ever needed it. It transfers *cleartext* passwords.

I am in favour of disabling all network access to boxes as they come from install. As it is, we have a bunch of things that are most often not necessary, and we're encouraging people (like poor misguided Nate here ;) to run protocols that do not encrypt passwords. Any proposal to disable things that listen to the network in our default setup will have my approval. Eivind.
