On the subject of submissions: possibly people have trouble submitting.
I just did - "rn" told me that the newsgroup was moderated, and that
it would mail my submission to the moderator. It then proceeded to
send to "comp.os.research" as a local user on my host. The mail was
undeliverable, and I looked you up in news.lists by hand.
[ Good point. I wish everyone's posting mechanism knew where to send it. ]
[ Postings should be sent to comp-os-research@sdcsvax.UCSD.EDU or for ]
[ those without domain mailers, {anywhere large}!sdcsvax!comp-os-research ]
One direction that we have to go, is towards support of audio and video
feeds. I expect that workstation vendors will offer conferencing packages
that put live video into multiple windows.
This differs from mere "faster, bigger" issues. If frames drop out, or if
the interframe delay is at all nonuniform, then customers are going to
be unhappy. This is not timesharing.
This isn't quite "real time", either. Demands are cyclic/predictable -
well, actually recomputable after each edit to the linkup pattern. Unless,
of course, the workstation is expected to do video compression and
decompression.
Since costs are still high, there is time to treat this as research rather
than development. The cost trends, and the benefits, tell me that it will
get developed.
[ Sounds interesting. I know almost nothing about this, and I'd like to ]
[ hear some more about it. It seems like we would need a small amount of ]
[ special hardware... Is ethernet "wide" enough to send video over without ]
[ a noticeable delay? ]
