With vorbis and ogg you CAN pass in read/write functions just fine, so I don't 
see the likeness. sndfile has a hack that somehow bypasses its incomplete fd 
handler..

And we can't assume a fd handler interface will work. files inside zip files 
don't have fds, and they are compressed, so you can't just pass the fd for the 
zip file in and expect it to work.

I was planning on lookin at sndfile's hacked api and working with it.. Here's 
what the dev has to say about his api:

I haven't actually taken a look at it yet, so I'm not sure if it'll do what we 
need. Most of sndfile uses specific functions that don't call into a vtable or 
anything so I'm honestly not sure how or if it works.

He has fd and filename handlers, he doesn't have a sane virtio interface 
though ;)
