My first dial-up setup was when pppd wasn't great at demand dialing (I
don't even remember seeing references to it then in the documentation or
HOWTOs,) and diald worked marvellously until I switched to DSL. You
don't think much about demand dialing over POTS once you have DSL or
cable modems as standard equipment.

That was what I meant by "having access to the modem", knowing that
sometimes somebody offers the *sage* advice of mucking around with the
permissions of the actual device rather than the correct move of putting
the users that have a reason for needing access in the correct groups.

I thought so. It was what made design sense, but y'never know when
somebody throws a design twist in that makes one put their foot deep in
their mouth by jumping to an expectation.
