Subject: Fusionsound audio driver
attached is a diff containing a audio driver for the FusionSound
library. This sound library is closely related to DirectFB and uses the
same transport (fusion) as DirectFB when running applications "remote",
i.e. over the network. As such, it natively redirects sound where
DirectFB redirects video. This may be handy for everyone using SDL over
DirectFB.
