Hi! Yes, it is a hard topic :)
As I see desktop sharing has two purpose. One is the thin client purpose, when the goal is that you can see an application running on another computer. Sun's Tarantella is a server which provides a common interface via java applet to many OS's remote desktop implemeting each rd protocols. I think for this purpose doesn't require flash. The second purpose, when you want to share your desktop to other, for example in a online classroom or support. In this case you need some other media format for example voice, text or data. This is comfortable to implement in flash with FMS/Red5. But in Flash you can not use customised codec. I dont know video codec for desktop sharing, but it could be very useful. I think it is very specific, because on the desktop you dont have motions, there are lots of static pixel etc. So it can be made very good if somebody would do it :) Br, Balazs On 11/23/06, Dario De Agostini <[EMAIL PROTECTED]> wrote:

Flash player can't "grab" desktop image. Even if it would capture it, it would be "useless" since it doesn't have a proper video encoder for such a video. (high resolution, small area changes, need for color compression and much more...) So Flash player can't (even if you use the mighty video driver it will NEVER give a good performance). If you can't use flash... what remains to you ? Java is the only solution which can be "installed" without having any particular client to be downloaded (like flash) and is multiplatform. This is why all "useful" alternatives to breeze are java based. you could also use windows ocx, which would give a very good performance, but it will be a MS Windows only solution.
