Vectored I/O

I just picked up the new issue of JDJ(Java Developers Journal) 02/04 and i found a very interesting article inside on Vectored I/O(scatter/gather) and multiplexing I/O. Has anyone had a chance to try out any of the new classes in the java.nio.* package yet?

I've been hovering around them, but I haven't found the need yet. My I/O requirements are pretty simple :)
