An earlier question still stands, and it is central: does UID == console session ID?
To me, this is very much like asking "Does UID == $DISPLAY"? And the answer of course is - not in general.
I am asking so that the answer is a documented-- and thought about-- instead of being a nebulous assumption. For one, it will be difficult to have true session-unique emulation support because those interfaces used /dev permissions with no concept of session, only uid and gid.
If the emu system daemon runs as root you, then /dev/dsp and friends would only need to be accessible by root assuming the emu system daemon passes the fd to the PA instances.
Eh, scrap that. We'd need to put ACL's on them anyway. The emu daemon would do additional checking though.
