I'm attending a SNIA meeting today to discuss a (cross-OS) data
integrity aware API. We'll see what comes out of that.

With the Linux hat on I'm still mainly interested in pursuing the
sys_dio interface Joel and I proposed last year. We have good experience
with that I/O model and it suits applications that want to interact with
the protection information well. libaio is also on my list.

But obviously any help and input is appreciated...
