It's very simple really. For rumposs I made OSS->Sun translation transparent
by integrating libossaudio directly into the source tree (note it had to be
integrated anyway, because of the modifications I stated in my previous mail).

You can do the same in a translator:

- Get ossaudio.c from rumposs, which includes all the necessary adjustments
(also just pushed GNU/Hurd fixes few minutes ago).

- Link it into your translator executable.

- Instead of forwarding ioctls to rump_sys_ioctl(), forward them to _oss_ioctl()
which is provided by ossaudio.c.

They provide libossaudio and then modify every OSS application to use 
_oss_ioctl()
and link with -lossaudio.
