There are a lot of things that X Consortium members have access to that are not made available to the public between releases. There's nothing wrong with that; that's what X Consortium members get for the money they provide. In X11R6, there will be Low Bandwidth X. This is derived from NCD's Xremote. It will do everthing Xremoted does now, and enhance it with host-side caching to cut down on the amount of round-trip data that has to be sent over the serial line. I've looked at enhancing 'term' to add the protocol-level compression. 'term' already implements functional equivalents for the lower two layers of Xremote. I've decided that it would be a waste of effort, given what's coming in X11R6, and the current ball-park schedules I've heard. There's a lot of other stuff to do with XFree86 in the meantime. -- David Wexelblat <dwex@mtgzfs3.att.com> (908) 957-5871 AT&T Bell Laboratories, 200 Laurel Ave - 3F-428, Middletown, NJ 07748 "In and around the lake, mountains come out of the sky.
