Yes, either ALSA, or for old firewire devices on top of 1394.

Yes with jack dummy-backend or a netjack: no local soundcard. No actual
audio/midi i/o

Asking the inverse is easier. in short: as user you only need jack if
you need inter-application routing.

Developers prefer jack because it offers a simple API, and it abstracts
a lot of complexities. e.g. it sets up realtime callbacks (every app
using ALSA directly would have to do that by itself).
