You need to do the math on this. Remember that a full 640x480 RGB stream at 30 frames per second runs 28 megabytes per second. That's more than twice what a 100 megabit network can pump. You can probably use Python to oversee this, but you might want to consider using lower-level code to control the actual hardware. If you are targeting Windows, for example, you could write a DirectShow graph to pump into a renderer that transmits out to a network, then another graph to receive from the network and display it. You can manage the network latency by adding a delays in the local graph. -- Tim Roberts, t...@probo.com Providenza & Boekelheide, Inc. -- http://mail.python.org/mailman/listinfo/python-list
