I think I will get the Cypress FX2 for the USB 
Interface and use a Xilinx chip for encoding the the
data coming from the Webcam or digital cam. On the
host side, I will write a simple web server which will
connect directly to the USB webcam's driver. The
clients will use a brower or a media player to view
the mpeg streamming out from the webserver. One thing
I am worrying about is the speed. I don't know if this
design will work or not. Any suggestions?
