Yes; I was thinking more of the stream-on-disk use case. A FEC pipe might be a nice undregrad software project for someone. Perhaps by default multiplex the data and the FEC, and then on the other end do one of two things: de-multiplex things into the next part of the pipe, or split the FEC stream into the original to one file and the original data into another. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
