Consider that windows will not utilize full network resources to stream it, so even if you do have a 100mb connection, the chances of your stream utilizing it would be slim to none, although a good idea, its doubtful unless you want a nice long serial cable...
still very doubtful on even a 1000Mb network. the limitations are not hardware but software. good luck, youll have to do your own coding, and it will take a high performance pc to be able to do much... not to mention getting the box to even load the stream.
if you can do it thats AWESOME! ill be following this thread to see how things come out. Good Luck.
