And there is the nasty part: > Patents. > ******** > > The BSD-Compress algorithm used for packet compression is the same as > that used in the Unix "compress" command. It is apparently covered by > U.S. patents 4,814,746 (owned by IBM) and 4,558,302 (owned by Unisys), > and corresponding patents in various other countries (but not > Australia).

Has anyone looked at it, if it could be modified to do zip compression instead. In addition to being patent-free it would improve performance? There is a libary for gzip routines which was used for ssh quite successfully, but I do not know how well it would sit into a kernel. The streams code does not apply FreeBSD, but as it is contaminated with a pretty restrictive copyright (no-no for an ISP: "...nor to provide a commercial service"). Is there something else than streams code which is covered by this copyright? -- Heikki Suonsivu, T{ysikuu 10 C 83/02210 Espoo/FINLAND, hsu@cs.hut.fi home +358-0-8031121 work -4513377 fax -4555276 riippu SN
