Yes...that would be me :)

They are free to distribute, but NOT free to distribute as part of a
product which charges customers $$$.

clipboardVdig is an updated version of scrapVdig (bug fixes, etc.....).
They should NOT both be installed at the same time (they'll conflict).
One should replace scrapVdig with clipboardVdig.....
Don't recall if I remembered to bump version number.

Yep..I'm aware of this.
Reason this is the case is that the copying of the large desktop area to a
small 160x120 window is slowww.
So, the operation is done less frequently and thus the "jerky" mouse movement.
It's a trade off: mouse lag with smooth movement vs. mouse keeping up but jumpy.
Now if everyone had G3s this may not be as big a problem..... (the copy
could be done more often)
AND if CU-SeeMe ever supports LARGE video, then this wouldn't be so much of
a problem, but the bandwidth used would increase greatly (but the desktop
would be more viewable at a large size video frame).

Good idea.
People have suggested taking this one step farther and displaying only a
user specified sectio of the desktop (I believe the Win based Snappy does

I can think of all sorts of neat ideas for QT movie streaming (educational
streaming, PR/Marketing/Product info streaming, etc...).
If more content sites would use the reflector (aka MPCS) as a draw (i.e.
brings people to their site), they could then have one or more continual
videos being displayed. So if Apple had their own reflector, they could
stream their recent Think Different ads or their slam Intel ads.
This is video only for now. Audio plays out the speaker, not out the wire.
One could hold mic up to speak or use a patch cable, but I'm working on a
software solution.

I'll send them all under separate cover...
