+Nice one David! Thank you so much :)
+
+I fixed the ACL issues in osspd the other week, so users should be able
+to use the /dev/dsp device quite happily now without any hacks.
+
+There are still some experimental patches (to cuse, kernel and osspd
+IIRC) that will enable mmap support which *should* be the final missing
+link for full OSS support in some games.
+
+At some point after mga2 we might want to consider dropping oss support
+fully, except via osspd, and thus soundwrapper might eventually be
+unneeded... but that discussion certainly doesn't need to happen today
+and it's not really a problem either way in my opinion - just a matter
+of how "progressive" we want to be :)
