Software mixing is a really nice feature for people with soundscards
that can't do hardware mixing, so if the OSS compatibility could
transparently do software mixing for apps using OSS api that would be
a very nice extension for a lot of people - I'd say that if NetBSD do
that they've got the right idea.
