I don't really see the problem with file descriptors, could you explain
it or give a relevant link about it ? Moreover, don't forget that on the
Hurd, filesystem nodes are the links to Hurd services, which means we
need at least one node somewhere to access the sound system (using Mach
interface directly would be an awfully wrong design).

Do you think it'd be possible to have JACK without an ALSA or OSS interface
on the Hurd ?
