In case somebody doesn't have the papers on this design (I assume you have all of the below), they are available from Heidemann's homepage at http://www.isi.edu/~johnh/ The ACM TOCS paper on stackable layers (the prime reference) is described on this page, along with references to postscript copies: http://www.isi.edu/~johnh/PAPERS/Heidemann93b.html > Are your vput changes available to be looked at anywhere? http://www.freebsd.org/~eivind/vput-proc.patch Eivind.
