I also have a positive experience with logitech 4000 Pro, both on Linux and Windows.
Another feature which was not mentioned here of this webcam is it's high sensitivity; when lights are off you can get good video.
Regarding streaming solutions: I once made tests with vlc , see: http://www.videolan.org and generally
it was OK , but I cannot compare with other solutions
as I did not try anything else.
(It is open source and works both in linux and windows ).
What I tried with VLC was http streaming (there are other types of streaming).
Regarding the market in the last two years: I am
following what happens and I agree that not much
was changed in recent 2 years (or even more).
This might change because now much higher upload bitrate
is more and more common abroad (also here), so transmitting
video in resolutions higher the CIF (CIF is 352x288) becomes more realistic Also the new H264 codec
which is more and more entering the market,
can contibute to better quality.
- Though I looked for it, I did not encounte a full list of webcams for video4linux 1 or video4linux 2 (there were some partial lists).

Oops you are right. I forgot to mention this but I'm not near the camera
to give its exact details - it's one of the cheapo cams which were available
already three years ago. I think it's just called "quickcam pro".

Is this the "Pro" or is there a "non-Pro" version? I've seen the "Pro" mentioned
many times in relation to Linux.
Thanks for the recommandation.

That's what I found too - there are either USB 1.1 cameras or "network webcams"
which provide AVI movies or auto-updated still frames when connected directly
over HTTP or somesuch, very expensive, apparently many of them come with
motors to remotely control their position, but also with nice high-resolution
(for instance, see http://tinyurl.com/9363c and pick "CITY" from the menu on
the left, notice the Luna-park under the bridge, then pick "Luna Park" from the
menu).

Thanks - that seems to explain the (disappointing) state of affairs as
I found it.
Maybe the most telling example is that I found the same model of camera I
bought three years ago still prominantly displayed on the shelfs today.
Still - can't I take advantage of the higher resolution available with some of
the cameras? I mean - if you look at zap.co.il you can find cameras with
640x480 resolution:
http://www.zap.co.il/models.asp?Sog=C-Webcam&DB66204=66205
Another confusing matter is the state of Video 4 Linux - should I track V4l2
or v4l (1)? Is there a comprehansive list of supported cameras (as opposed to
supported cheaps)?
And one last bit - does anyone here have experience in streaming webcam output
between Linux and Windows XP?
