slide show

When I first heard about a new slide show capability in the
latest beta release of CU-SeeMe, the concept that came to mind
for me was quite different from what the system turned out to
be. For my purposes, it would be ideal to be able to capture
a portion of what's displayed on the screen to incorporate into
a "slide show" to accompany the cuseeme video. This would allow
a user to do what the current slide show facility does, but it
would also allow me to capture a screen from a powerpoint
presentation or a Mosaic display and include it in the show.
That's what I'd really like to do for remote presentations.

Is there some clever way to do this with the current mix of
capabilities? It seems that pointing a video camera at
another video screen is plagued by loss of resolution,
flicker (which has been discussed in some detail), and
simply isn't the clean way to accomplish this. Likewise
printing out the screen, then pointing a camera at the
printout would seem cumbersome, wasteful and lossy.

Am I missing something obvious? How about something not
so obvious? Are there other approaches to displaying
slides during a cuseeme presentation?

If not, I'd like to add to the wishlist a capability for
capturing part of the screen to be incorporated into
a cuseeme slideshow.
